What is Cryptocurrency?


What is Cryptocurrency?
Cryptocurrency is a decentralised digital asset that uses cryptographic methods to enable peer-to-peer value transfer without financial intermediaries.
Cryptocurrencies function as programmable digital money. Each unit is secured using cryptographic hash functions, verified through distributed consensus mechanisms such as Proof of Work (PoW) or Proof of Stake (PoS), and recorded on public blockchains like Bitcoin or Ethereum.
A blockchain is a linear, append-only database. It stores every transaction in an immutable format. Bitcoin (BTC) was the first cryptocurrency, created in 2009 by the pseudonymous developer Satoshi Nakamoto. Bitcoin introduced digital scarcity and a fixed maximum supply of 21 million coins.
There are over 9,500 cryptocurrencies in circulation as of July 2025. Each differs by:
Monetary policy (fixed vs. inflationary supply)
Consensus protocol (PoW vs. PoS)
Utility (store of value, smart contracts, stablecoins)
Coins like Bitcoin and Litecoin operate on their own blockchain. Tokens like USDT or UNI operate on platforms like Ethereum. Stablecoins are pegged to fiat currencies like the U.S. Dollar and are often used in digital payments and trading pairs.
According to a 2024 Pew Research Center study, 17% of U.S. adults have traded or used crypto assets. The IRS classifies cryptocurrencies as property under IRS Notice 2014-21, subject to capital gains tax when sold or exchanged.
Crypto transactions are secured through private-public key encryption. Each wallet address holds an alphanumeric identifier linked to a public key. Only the corresponding private key can authorise transfers, making security fundamental.
Unlike U.S. bank accounts, there is no FDIC protection for crypto holdings. Users must manage digital wallets, cold storage devices, and smart contract risk directly. Popular U.S.-based exchanges include Coinbase, Kraken, and Gemini, all regulated under FinCEN and state-level money transmission laws.
Cryptocurrency redefines how digital value is stored, transmitted, and programmed. It enables permissionless finance, cross-border remittances, tokenised asset ownership, and decentralised application logic without reliance on traditional banking infrastructure.

What is Digital Currency?
Digital currency is a non-physical monetary unit that exists exclusively in electronic form and enables value transfer over digital networks. It differs from traditional cash by lacking a physical medium, existing only as ledger entries within software-based financial systems.
There are three primary types of digital currency, each defined by its issuing entity and operational infrastructure:
Central Bank Digital Currencies (CBDCs):
Issued by sovereign monetary authorities and represent national fiat currencies in a digital format.Example: Digital Yuan (People’s Bank of China)
In the U.S., the Federal Reserve is exploring a Digital Dollar under Project Hamilton
Cryptocurrencies:
Decentralised digital assets secured by blockchain protocols.Examples include Bitcoin, Ethereum, and Cardano
Operate independently of governments or banks
Subject to regulatory classification by IRS, SEC, and CFTC
Virtual Currencies:
Platform-specific currencies used in digital environments or gaming ecosystems.Examples: Robux (Roblox), V-Bucks (Fortnite), Linden Dollars (Second Life)
Controlled by centralised private entities
Not convertible to fiat by default
In the U.S., FinCEN requires businesses handling digital currency to register as Money Services Businesses (MSBs). The IRS classifies cryptocurrencies as property, not currency, and requires capital gains reporting on taxable events.
Key applications of digital currency in the U.S. include:
Real-time payments via P2P apps like Venmo and CashApp
Cross-border transfers using blockchain rails like Stellar or RippleNet
Smart contract automation in decentralised finance (DeFi)
Asset tokenisation for equities, real estate, and intellectual property
Digital currencies function without physical notes or coins. They rely on encryption, digital wallets, and secure networks to process, store, and validate transactions. Every form—whether CBDC, crypto, or virtual—shares the core attribute of programmability and online operability.
What are the types of cryptocurrency?
There are three main types of cryptocurrency: coins, tokens, and stablecoins. Each type differs by blockchain dependency, monetary function, and utility.
Cryptocurrencies are categorised by architecture and intended use. Coins operate on their native blockchain. Tokens are deployed via smart contracts on existing blockchains. Stablecoins aim to maintain price stability by pegging value to reserve assets.
1. Coins
Coins are native digital currencies created to power their own blockchain protocols. Examples include:
Bitcoin (BTC) — store of value, fixed supply
Litecoin (LTC) — fast transactions, low fees
Dogecoin (DOGE) — inflationary model, meme currency
Coins are mined or validated through consensus algorithms like Proof of Work or Proof of Stake.
2. Tokens
Tokens are programmable assets that exist on external blockchains like Ethereum or Solana. Tokens follow standards like ERC-20 (fungible), ERC-721 (non-fungible), or BEP-20 (Binance Smart Chain). Token use cases include:
Utility tokens (e.g. UNI, LINK) — enable access to services
Governance tokens (e.g. AAVE, MKR) — voting rights on protocol upgrades
NFTs — digital ownership of assets like art or identity
According to CoinMarketCap (Q2 2025), over 70% of active cryptocurrencies are tokens.
3. Stablecoins
Stablecoins are price-pegged digital assets designed to reduce volatility. Most are pegged to the U.S. Dollar and used in trading, remittances, and DeFi. Categories include:
Fiat-backed (e.g. USDT, USDC) — backed by cash reserves
Crypto-collateralised (e.g. DAI) — backed by over-collateralised crypto
Algorithmic (e.g. FRAX) — governed by supply-adjusting smart contracts
As of July 2025, USDT and USDC account for over $140 billion in daily trading volume, according to CoinGecko.
How does cryptocurrency work?
Cryptocurrency works through decentralised blockchain networks that verify, record, and secure peer-to-peer transactions using cryptographic protocols without banks or central authorities.
Each transaction is added to a block, which is validated by a network of nodes. Once verified, the block is permanently appended to the blockchain. This structure prevents double-spending, ensures data immutability, and maintains a public, chronological ledger.
Cryptocurrencies use cryptographic techniques, such as hash functions, public-key encryption, and digital signatures, to validate identities and secure data. No physical coins exist. All cryptocurrency units are represented as digitally signed ledger entries.
There are two primary blockchain consensus mechanisms that determine how cryptocurrency networks process transactions:
Proof of Work (PoW):
Miners solve complex mathematical puzzles to validate transactions
Used by Bitcoin, Litecoin, Dogecoin
High energy consumption, high security
Proof of Stake (PoS):
Validators are selected based on the amount of cryptocurrency they stake
Used by Ethereum, Solana, Cardano
Energy-efficient and scalable
Once verified, a transaction becomes visible across all blockchain nodes. No single party can alter the data without majority consensus, which ensures decentralisation and data integrity. Each user sends or receives cryptocurrency via a digital wallet containing a public address and a private key. The private key authorises ownership and controls asset transfer.
In the U.S., these processes are regulated by agencies like the SEC (for investment contracts), the CFTC (for crypto-commodities), and FinCEN (for money service providers). Platforms such as Coinbase, Kraken, and Gemini act as compliant intermediaries offering U.S. residents secure access to blockchain networks.
Cryptocurrency networks run 24/7, process irreversible transactions, and require no human settlement processes. All value exchange occurs directly between participants, governed entirely by code-based rules stored on decentralised public infrastructure.

What is blockchain in cryptocurrency?
Blockchain is a distributed digital ledger that records all cryptocurrency transactions in sequential blocks across a decentralised network of computers.
Every cryptocurrency relies on blockchain to ensure transparency, traceability, and data integrity. A blockchain functions as a consensus-based transaction history, where each block stores a group of verified transactions along with a timestamp and cryptographic hash of the previous block.
This structure creates a chain of blocks that cannot be altered retroactively without revalidating all subsequent blocks—a process that is computationally and economically prohibitive.
Key Components of Blockchain in Cryptocurrency:
Blocks:
Store batches of transactions, a cryptographic hash, and metadata
Example: Bitcoin blocks are added every 10 minutes
Ethereum blocks are added every 12 seconds
Nodes:
Independent computers running the full blockchain software
Validate and relay transactions
Maintain decentralisation by distributing ledger copies globally
Consensus Mechanism:
Determines how new blocks are validated and added
Includes Proof of Work (PoW) and Proof of Stake (PoS)
Hashing Function:
Ensures data integrity using algorithms like SHA-256 (Bitcoin)
Any alteration changes the entire block hash, signalling tampering
Immutability:
Once added, blocks cannot be edited
Maintains a verifiable and irreversible record of every crypto transfer
According to the MIT Media Lab, blockchain’s cryptographic and distributed design makes it suitable for tamper-proof financial applications, asset tokenisation, and decentralised smart contracts. The U.S. Treasury recognises public blockchains as financial infrastructure components in emerging crypto-finance ecosystems.
Blockchains also enable permissionless access, allowing any user to broadcast transactions, verify data, and interact with the network without approval from a central authority.
In cryptocurrencies, blockchain eliminates the need for banks, clearing houses, or intermediaries. Instead, code enforces consensus rules, and network participants maintain ledger integrity collectively.

What is a crypto wallet and how does it work?
A crypto wallet is a digital tool that stores cryptographic keys and allows users to send, receive, and manage cryptocurrency on blockchain networks.
Crypto wallets do not store actual coins. Instead, they manage public keys and private keys that control ownership of blockchain-based assets. The public key is used to receive funds, while the private key is required to authorise outgoing transactions.
Each wallet interacts directly with the blockchain to check balances, broadcast transactions, and manage cryptographic signatures. Wallets are essential for accessing decentralised networks without intermediaries.
Types of Crypto Wallets
Hot Wallets (Online):
Connected to the internet
Suitable for frequent trading or transfers
Examples: Coinbase Wallet, MetaMask, Trust Wallet
Vulnerable to phishing, malware, and exchange breaches
Cold Wallets (Offline):
Disconnected from the internet
Ideal for long-term storage of high-value assets
Examples: Ledger Nano X, Trezor Model T, paper wallets
Immune to online hacks but vulnerable to physical loss
Custodial Wallets:
Controlled by third-party providers such as Coinbase or Kraken
User does not control private keys
Regulated as Money Services Businesses (MSBs) under FinCEN in the U.S.
Non-Custodial Wallets:
User retains full control of private keys
Required for DeFi platforms, staking, and token swaps
No recovery if private keys are lost
Wallets typically support multiple blockchain networks (e.g. Ethereum, Solana, Binance Smart Chain). They also provide features such as seed phrase recovery, token swapping, NFT storage, and staking interfaces.
According to Chainalysis (2024), over 72% of crypto users in the U.S. store their assets in custodial wallets, while long-term holders prefer cold storage for improved security.
In cryptocurrency, “not your keys, not your coins” reflects the principle that private key ownership equals asset control. Users who fail to secure their wallets risk irreversible asset loss due to forgotten passwords, lost devices, or scams.
Is cryptocurrency legal in the U.S.?
Cryptocurrency is legal in the United States, but it is regulated under multiple federal and state laws depending on its use, classification, and underlying function.
There is no single regulatory body overseeing cryptocurrency in the U.S. Instead, various federal agencies apply different legal frameworks based on whether crypto assets are used as securities, commodities, property, or payment instruments. The legality of cryptocurrency depends on its classification and the nature of its use.
Key Regulatory Authorities in the U.S.:
Securities and Exchange Commission (SEC):
Treats some tokens as investment contracts
Enforces disclosure requirements under the Howey Test
Filed enforcement actions against projects like Ripple (XRP) and Terraform Labs
Commodity Futures Trading Commission (CFTC):
Classifies Bitcoin and Ethereum as commodities
Regulates crypto derivatives, futures, and margin trading
Internal Revenue Service (IRS):
Recognises crypto as property under Notice 2014-21
Requires capital gains reporting on disposals, trades, and earnings

Financial Crimes Enforcement Network (FinCEN):
Regulates crypto businesses as Money Services Businesses (MSBs)
Enforces Anti-Money Laundering (AML) and Know Your Customer (KYC) laws
Requires reporting of suspicious transactions via Form 8300 or SARs
Office of Foreign Assets Control (OFAC):
Prohibits transactions with sanctioned wallets and blacklisted entities
Enforces economic sanctions compliance for U.S.-based crypto exchanges
State-Level Compliance:
U.S. states also impose crypto-specific laws.
New York requires a BitLicense for crypto operations
Texas, Wyoming, and Florida have more permissive frameworks
California proposes legislation for stablecoin oversight and consumer protection
According to a 2024 Congressional Research Service (CRS) report, over 22 million U.S. residents engage with cryptocurrencies annually. Legal use includes trading, payments, DeFi, NFTs, and remittances—provided users comply with applicable tax, AML, and securities rules.
While the U.S. government does not issue cryptocurrency as legal tender, owning, buying, mining, or selling digital assets remains fully legal when performed through compliant platforms.
Is cryptocurrency legal in Europe?
Cryptocurrency is legal across Europe and regulated under the EU’s Markets in Crypto-Assets Regulation (MiCA), with national frameworks supporting legal trading, custody, and taxation.
The European Union views cryptocurrencies as digital representations of value and has established a harmonised legal framework to oversee trading platforms, wallet providers, and stablecoins. Each member state applies its own tax and licensing policies, but all adhere to common AML and investor protection standards.
EU-Level Legal Framework:

In Asia, Japan, South Korea, Singapore, and UAE lead in regulatory clarity and institutional adoption. China and Afghanistan enforce blanket bans, while India and Southeast Asia follow mixed models of taxation and partial authorisation. The region reflects a spectrum from legal certainty to policy ambiguity, shaped by each nation’s fiscal and technological priorities.
Is cryptocurrency safe?
Cryptocurrency is secure at the protocol level, but user safety depends on storage practices, platform reliability, and risk awareness.
Most cryptocurrencies use blockchain cryptography, decentralised consensus, and public-private key encryption, making the underlying networks highly resistant to tampering. However, the user-facing environment—wallets, exchanges, smart contracts—exposes risks not protected by the blockchain itself.
Key Risks in Cryptocurrency Use:
Private Key Loss:
Wallet access is secured by private keys
If lost or forgotten, funds are irretrievable
No password reset or institutional recovery exists
Exchange Hacks:
Centralised exchanges are high-value targets for attackers
Over $3.8 billion was stolen from exchanges globally in 2022, according to Chainalysis
U.S.-based exchanges like Coinbase and Gemini are FDIC-insured for USD deposits, but not for crypto assets
Phishing and Social Engineering:
Fake apps, fraudulent airdrops, and deceptive links compromise wallets
Users are responsible for verifying websites, transactions, and seed phrase storage
Smart Contract Exploits:
Decentralised finance (DeFi) protocols can be vulnerable to code-level bugs
Flash loan attacks, reentrancy bugs, and oracle manipulation are common vectors
Volatility and Market Manipulation:
Prices are speculative and can drop over 70% in short periods
Wash trading, pump-and-dump schemes, and whale actions distort fair market valuation
Security Best Practices for U.S. Users:
Use hardware wallets (e.g. Ledger, Trezor) for long-term storage
Enable multi-factor authentication (MFA) on exchange accounts
Verify contract addresses and use trusted aggregators (e.g. CoinGecko, Etherscan)
Never store private keys or seed phrases online or in email inboxes
Avoid interacting with unvetted dApps and unknown tokens
While blockchains like Bitcoin and Ethereum are mathematically secure, cryptocurrency safety ultimately depends on user decisions. Unlike traditional banking systems, there are no institutional protections, fraud reversals, or legal guarantees. Cryptocurrency offers sovereignty, but it requires operational discipline.
What are the benefits of cryptocurrency?
Cryptocurrency offers decentralisation, financial access, fast settlement, low-cost transactions, and programmable money without reliance on banks or governments.
The utility of cryptocurrency arises from its blockchain foundation, global accessibility, and open architecture. In the U.S. and globally, crypto enables digital ownership, alternative finance models, and peer-to-peer value exchange with reduced institutional friction.
Primary Benefits of Cryptocurrency:
Decentralisation:
Operates without central banks or monetary authorities
Trust is enforced by open-source code and public consensus mechanisms
Bitcoin and Ethereum nodes are distributed across 100+ countries
Financial Inclusion:
Enables unbanked users to access financial tools using only a smartphone
In the U.S., over 5.9 million adults were unbanked in 2023 according to the FDIC
Crypto wallets require no credit score, identity check, or minimum deposit
Fast, Borderless Transactions:
Transfers occur 24/7 without banking hours
Settlement is near-instant on blockchains like Solana and Stellar
Ideal for cross-border remittances, freelancer payments, and emergency aid
Lower Transaction Costs:
Many Layer-2 networks offer transfers below $0.01
Eliminates intermediary fees charged by banks, credit card processors, and SWIFT networks
Ownership and Sovereignty:
Users control funds directly through private keys
No freezing, censoring, or third-party custody is required
“Not your keys, not your coins” reflects financial self-custody
Programmable Assets:
Smart contracts automate lending, borrowing, insurance, and yield farming
Power decentralised apps (dApps) and protocols like Uniswap, Aave, Compound
Reduces paperwork and manual financial operations
Portfolio Diversification:
Correlation between crypto and traditional equities is low
Bitcoin is increasingly used as an inflation hedge and store of value by U.S. investors
Over 14% of Gen Z investors in the U.S. hold crypto assets (Charles Schwab, 2024)
While cryptocurrency introduces risks, it also transforms access, efficiency, and control in digital finance. Users benefit from direct asset custody, reduced fees, global transferability, and financial participation without central approval.
What are the drawbacks of cryptocurrency?
The main drawbacks of cryptocurrency include volatility, regulatory uncertainty, lack of consumer protection, energy usage, and limited mainstream adoption.
Despite offering decentralisation and programmability, cryptocurrencies carry significant risks that affect retail investors, regulators, financial institutions, and software developers. These drawbacks impact scalability, usability, and long-term integration with traditional financial systems.
Key Drawbacks of Cryptocurrency:
Price Volatility:
Cryptocurrencies can lose over 60% of market value in weeks
Unstable pricing deters use in payroll, savings, and retail payments
Affects collateralisation in lending protocols and financial planning
Regulatory Uncertainty:
SEC, CFTC, IRS, FinCEN, and state agencies issue overlapping rules in the U.S.
Projects may face enforcement actions without clear legal status
Sudden policy changes increase risk for investors and developers
Lack of Consumer Protections:
No FDIC insurance or institutional fraud protection
Scams, phishing attacks, and smart contract exploits can cause unrecoverable losse
No chargebacks or dispute resolution mechanisms
Energy Consumption (PoW Networks):
Bitcoin mining consumes over 95 TWh/year, comparable to the energy use of Sweden
Environmental criticism from ESG-focused investors and policymaker
PoS chains address this but PoW remains dominant for Bitcoin
User Experience and Complexity:
Wallets require private key management
Blockchain addresses are non-human readable
Mistakes (e.g. sending to the wrong address) are irreversible
Scalability and Speed Issues:
Base-layer networks like Ethereum and Bitcoin process fewer than 20 TPS
Congestion leads to high gas fees during peak usage
Requires Layer-2 adoption to support mass usage
Illicit Activity Concerns:
Crypto used in ransomware, darknet markets, and sanctions evasion
Triggers enhanced scrutiny from regulators and law enforcement agencies
Blockchain forensics tools (e.g. Chainalysis, Elliptic) attempt to mitigate this
Limited Acceptance in Retail and Banking:
Most U.S. merchants do not accept direct crypto payments
Banks restrict interaction with certain exchanges and DeFi protocols
Stablecoin adoption still faces regulatory pushback
Cryptocurrency offers financial autonomy but lacks the legal, technical, and systemic safeguards found in regulated finance. These drawbacks must be addressed for broader adoption, regulatory harmony, and consumer trust.
What are the risks of cryptocurrency?
Cryptocurrency carries financial, technical, legal, and security risks due to market volatility, decentralised protocols, lack of federal protection, and irreversible transactions.
While blockchain networks are cryptographically secure, most risks stem from how users store assets, interact with platforms, or engage with unregulated ecosystems. In the U.S., the absence of FDIC insurance, SEC investor protections, and unified regulatory oversight increases exposure for retail participants.
Key Risks Associated with Cryptocurrency:
Market Volatility:
Prices are highly speculative
Bitcoin dropped over 75% during the 2022 bear market
Crypto values are driven by sentiment, liquidity cycles, and macroeconomic shifts
Loss of Private Keys:
Digital wallets rely on private keys to access funds
Lost or stolen keys result in permanent asset loss
No institutional recovery or password reset exists
Exchange Hacks and Custodial Risk:
Centralised platforms have been breached (e.g. Mt. Gox, FTX)
Over $3.8 billion stolen in 2022 alone (Chainalysis)
U.S. platforms may offer FDIC protection for fiat but not for crypto balances
Fraud and Scams:
Rug pulls, Ponzi tokens, and phishing sites target inexperienced users
Fake airdrops and social engineering compromise wallets
FTC reports over $1 billion in crypto fraud losses in the U.S. from 2021–2023
Smart Contract Vulnerabilities:
Bugs in DeFi protocols can be exploited for multi-million dollar thefts
Flash loan exploits, logic errors, and unchecked oracles increase systemic risk
Code audits do not guarantee security
Regulatory Uncertainty:
Crypto is classified as property, commodity, or security depending on use
SEC, CFTC, FinCEN, and IRS impose overlapping compliance burdens
Legal action against platforms or tokens can freeze assets or cause price crashes
Irreversible Transactions:
All blockchain transfers are final
Mistyped addresses, wrong amounts, or scams cannot be reversed
No chargebacks, dispute resolution, or fraud reimbursements
While cryptocurrency empowers users with direct control over digital assets, it also eliminates traditional safeguards like custodial recovery, institutional guarantees, and legal recourse. Users must weigh these risks when participating in the crypto economy and implement strong operational security measures.

Each example represents a specific function in the crypto ecosystem. Bitcoin offers scarcity and decentralisation. Ethereum enables programmability. Stablecoins like USDT provide transactional stability. DeFi tokens like UNI and LINK support autonomous financial operations.

What is DeFi in cryptocurrency?
DeFi, or decentralised finance, is a blockchain-based financial system that replaces banks with smart contracts to enable peer-to-peer lending, trading, and asset management without intermediaries.
DeFi operates on public blockchain networks, primarily Ethereum, and uses programmable code to automate financial operations. It removes the need for traditional institutions like banks, brokerages, and clearing houses by executing transactions via smart contracts.
DeFi platforms replicate traditional financial functions such as savings, loans, insurance, and exchanges—offering users full asset control through non-custodial crypto wallets.
Core Components of DeFi:
Decentralised Exchanges (DEXs):
Examples: Uniswap, SushiSwap, Curve
Users swap tokens directly from their wallets using automated market makers (AMMs)
Lending Protocols:
Examples: Aave, Compound, MakerDAO
Users deposit crypto to earn interest or borrow against collateral without credit checks
Stablecoins:
Used for liquidity, trading, and collateral
Examples: DAI (crypto-collateralised), USDC, USDT
Yield Aggregators:
Examples: Yearn Finance, Beefy Finance
Optimise yield farming strategies by reallocating capital across DeFi protocols
Synthetic Assets & Derivatives:
Examples: Synthetix, dYdX
Offer exposure to real-world assets like stocks, commodities, or indexes using tokenised instruments
DeFi transactions are governed entirely by code. There is no central authority, customer support, or institutional guarantee. All user funds are managed via public-key cryptography and interact directly with on-chain protocols.
According to DappRadar (Q2 2025), total value locked (TVL) in DeFi exceeds $85 billion, with U.S.-based users accounting for 28% of global wallet interactions. However, DeFi platforms are not FDIC insured and are subject to smart contract risks, impermanent loss, and potential regulatory enforcement.
DeFi expands access to programmable financial tools globally. It enables self-custodied users in the U.S. to earn yield, borrow capital, and trade assets without KYC or credit scores, but requires technical literacy and risk management.
What is Bitcoin?
Bitcoin is a decentralised digital currency that enables peer-to-peer transactions without banks, using cryptographic protocols and a public blockchain.
Bitcoin was introduced in 2009 by the pseudonymous developer Satoshi Nakamoto. It operates on a Proof of Work (PoW) consensus mechanism and is the first cryptocurrency to solve the double-spending problem without a central authority. Bitcoin is not issued by any government, and its supply is capped at 21 million coins, making it digitally scarce.
Key Attributes of Bitcoin:
Blockchain Network:
Transactions are recorded in a public ledger
Verified by miners using the SHA-256 hashing algorithm
A new block is added approximately every 10 minutes
Monetary Policy:
Fixed maximum supply: 21 million BTC
Halving event every 210,000 blocks (~4 years) reduces miner rewards
Controlled issuance schedule makes Bitcoin deflationary by design
Use Cases:
Store of value (“digital gold”)
Medium of exchange for goods and services
Inflation hedge in high-debt economies
Cross-border remittances without intermediaries
Wallet and Custody:
Bitcoin is stored in digital wallets via public/private key pairs
Can be held on hardware wallets (e.g. Ledger, Trezor) or exchange platforms (e.g. Coinbase)
Regulatory Classification (USA):
Treated as a commodity by the CFTC
Treated as property by the IRS, subject to capital gains tax
Recognised by the SEC as not a security
Bitcoin’s market dominance often exceeds 40% of the total crypto market cap. As of July 2025, over 46 million Americans hold some form of Bitcoin, according to Pew Research.
Bitcoin is decentralised, censorship-resistant, borderless, and transparent. It requires no bank accounts, supports financial autonomy, and has become a macroeconomic hedge asset in both retail and institutional portfolios.
What is Ethereum?
Ethereum is a decentralised blockchain platform that enables smart contracts and powers decentralised applications (dApps) using its native cryptocurrency, Ether (ETH).
Launched in 2015 by Vitalik Buterin and a team of developers, Ethereum introduced programmable blockchain logic, allowing developers to build applications beyond basic transactions. It is the foundation of decentralised finance (DeFi), non-fungible tokens (NFTs), and on-chain governance systems.
Ethereum is not just a currency—it is a general-purpose blockchain that supports computation, state, and logic via smart contracts. These are self-executing code modules stored directly on the Ethereum Virtual Machine (EVM), enabling autonomous financial tools and protocols.
Key Attributes of Ethereum:
Native Asset – Ether (ETH):
Used to pay gas fees for executing smart contracts and transactions
Functions as a store of value, utility token, and staking asset
ETH is the second-largest cryptocurrency by market cap after Bitcoin
Consensus Mechanism:
Originally launched with Proof of Work
Transitioned to Proof of Stake (PoS) in 2022 via the Ethereum Merge
Validators are selected based on ETH stake rather than computational power
Smart Contract Functionality:
Allows automation of lending, insurance, trading, and DAOs
Hosts most of the DeFi ecosystem: Uniswap, Aave, MakerDAO, Curve
Code is immutable once deployed, with execution enforced by consensus
Decentralised Applications (dApps):
Ethereum powers thousands of applications in DeFi, gaming, NFTs, identity, and DAO governance
Development is supported by frameworks like Solidity, Remix, and Hardhat
Scalability Solutions:
High gas fees and network congestion led to the rise of Layer-2 solutions
Popular rollups include Arbitrum, Optimism, and zkSync
Reduce transaction cost while retaining Ethereum’s security guarantees
Regulatory Context in the U.S.:
Classified as a commodity by the CFTC
Recognised as property by the IRS for tax reporting
SEC has not explicitly declared ETH a security post-Merge, leaving ambiguity
As of Q3 2025, Ethereum secures over $65 billion in DeFi total value locked (TVL) and remains the most widely used blockchain for smart contract innovation and decentralised finance in the United States.
How to Buy Cryptocurrency
To buy cryptocurrency, create an account on a regulated exchange, complete identity verification, deposit fiat funds, and place a market or limit order for your chosen asset.
In the U.S., cryptocurrency purchases must follow federal compliance standards, including KYC (Know Your Customer) and AML (Anti-Money Laundering) checks. Most users begin by registering with a licensed platform that supports USD deposits, secure custody, and fiat-to-crypto trading.
Step-by-Step: Buying Cryptocurrency in the U.S.
Choose a Regulated Exchange
Examples: Coinbase, Kraken, Gemini, Robinhood Crypto
Must be registered as a Money Services Business (MSB) with FinCEN
Ensure state-level compliance (e.g. BitLicense for New York residents)
Create and Verify Your Account
Submit legal name, email, and secure password
Upload government-issued ID and proof of address
Verification usually takes 5–15 minutes for individuals
Deposit U.S. Dollars (USD)
Supported methods: Bank transfer (ACH/wire), Debit card, Apple Pay
Some platforms also allow PayPal or credit cards (fees may vary)
Select a Cryptocurrency
Most popular: Bitcoin (BTC), Ethereum (ETH), Solana (SOL), Tether (USDT)
Check price charts, market depth, and liquidity before purchasing
Place an Order
Market order: Immediate purchase at current market price
Limit order: Buy only when price hits a target
Orders execute once funds clear and identity is verified
Secure Your Assets
Withdraw crypto to a non-custodial wallet for self-custody (e.g. MetaMask, Ledger)
Or keep it on the exchange if you prefer ease of access (with MFA enabled)
Legal and Tax Considerations
All transactions are reported to the IRS as property acquisitions
Capital gains/losses apply when assets are sold, swapped, or spent
Some exchanges issue Form 1099-B or 1099-MISC for reporting
According to a 2024 Pew Research study, over 17% of U.S. adults have bought cryptocurrency, with Coinbase being the most-used platform. Beginners are advised to use regulated custodians, enable 2FA, and document every transaction for accurate tax filing.
Is crypto a good investment?
Cryptocurrency is a high-risk, high-reward investment that offers growth potential, portfolio diversification, and inflation hedging—but it also exposes investors to volatility, regulatory risk, and capital loss.
Cryptocurrencies like Bitcoin and Ethereum have delivered significant historical returns but are speculative in nature. Their value depends on network adoption, market liquidity, technological development, and macroeconomic sentiment.
Potential Benefits as an Investment:
High Return Potential:
Bitcoin increased from $0.08 (2010) to over $65,000 (2021) before retracing
Ethereum gained over 40,000% between 2015–2021
Early-stage tokens offer asymmetric upside, but higher risk
Portfolio Diversification:
Low correlation to traditional assets like equities or bonds
Hedge against currency debasement and monetary inflation
Institutional firms like Fidelity, BlackRock, and MicroStrategy hold crypto
Access to Emerging Sectors:
Exposure to decentralised finance (DeFi), non-fungible tokens (NFTs), and tokenised assets
Investment vehicles include spot tokens, stablecoins, ETFs, and DeFi yield protocols
Ethereum, Solana, and Avalanche power decentralised applications and smart contracts
Risks to Consider:
Volatility:
Prices can fluctuate 20–50% in a single week
No intrinsic valuation models (unlike stocks or bonds)
Emotional trading amplifies price swings
Regulatory Exposure (USA):
SEC may classify some tokens as securities
IRS imposes capital gains tax on every transaction or trade
Future policy decisions can restrict access or impose additional burdens
Security & Custody Risk:
Investors must protect private keys or use regulated custodians
Hacks, rug pulls, and exchange collapses can lead to permanent losses
No FDIC or SIPC insurance for crypto assets
Illiquidity and Exit Risk:
Some low-cap tokens trade on unregulated exchanges
Poor liquidity can impact exit timing or lead to slippage
Stablecoins may lose peg under stress (e.g. TerraUSD crash, May 2022)
U.S. Investor Insights:
According to a 2024 Charles Schwab survey, 14% of Gen Z and 11% of Millennials include crypto in their retirement accounts. SEC-approved Bitcoin ETFs launched in 2024 increased institutional access, but retail investors are advised to limit allocation to 1%–5% of portfolios unless risk tolerance is high.

How to make money with cryptocurrency?
You can make money with cryptocurrency by trading, investing, staking, yield farming, lending, mining, or participating in blockchain-based reward systems.
Crypto income strategies fall into two categories: active methods (e.g. trading, arbitrage) and passive methods (e.g. staking, HODLing, DeFi yield). Each strategy varies in risk, complexity, regulatory exposure, and required capital.
Main Ways to Make Money with Cryptocurrency:
Buy and Hold (HODLing):
Long-term investment strategy
Popular for Bitcoin, Ethereum, and Layer-1 tokens
Requires cold storage security and capital gains tax reporting
Trading:
Involves buying low and selling high over short timeframes
Strategies include day trading, swing trading, and arbitrage
Requires deep knowledge of technical analysis, liquidity pairs, and volatility management
Staking:
Lock up Proof-of-Stake (PoS) assets like ETH, ADA, or SOL to earn yield
Typical APY ranges from 3%–12%, depending on network inflation and lockup duration
U.S. staking income is considered taxable as ordinary income upon receipt
Yield Farming:
Provide liquidity to DeFi protocols like Uniswap, Aave, or Curve
Earn rewards in native tokens and trading fees
Carries risks of impermanent loss, smart contract bugs, and rug pulls
Lending Crypto:
Lend stablecoins or tokens via protocols like Compound, MakerDAO, or Celsius (ceased)
Yields vary based on demand and borrower risk
May require overcollateralised deposits and carry counterparty risk
Mining:
Earn rewards by validating transactions on Proof-of-Work networks like Bitcoin
Requires ASIC hardware, electricity, and mining pool access
Profits depend on hash rate, block rewards, and energy costs
Airdrops & Token Rewards:
Free token distributions to wallet holders for holding, staking, or using dApps
Examples: Uniswap (UNI), Arbitrum (ARB), Optimism (OP)
Income is taxable at the time of receipt under IRS guidance
NFT Creation & Sale:
Mint, market, and sell digital assets on platforms like OpenSea, Rarible, or Zora
Success depends on branding, rarity, utility, and community demand
Tax Considerations (U.S.):
All crypto earnings—staking rewards, airdrops, interest, or profits—are taxable
Capital gains apply when assets are sold or swapped
IRS Forms: 1099-B, 8949, Schedule D, and Form 1040
What are the safest ways to earn with crypto?
The safest ways to earn with cryptocurrency include staking on major networks, using regulated interest-earning platforms, providing liquidity to audited DeFi protocols, and holding blue-chip assets long-term.
Earning safely in crypto requires minimising exposure to custodial risk, smart contract exploits, asset volatility, and regulatory non-compliance. In the U.S., only some earning methods align with tax clarity and consumer protections.
Low-Risk Earning Strategies in Crypto:
Staking on Proof-of-Stake (PoS) Blockchains:
Lock assets like Ethereum (ETH), Cardano (ADA), or Solana (SOL)
Earn network-native rewards in return for securing the chain

Monitor impermanent loss and protocol usage levels
Participating in Verified Airdrops and Rewards:
Claim free tokens from credible projects (e.g. Optimism, Arbitrum)
Avoid phishing links and impersonation scams
Verify project legitimacy through Etherscan, CoinGecko, or GitHub commits
Taxable as income at fair market value when received
Safety Recommendations for U.S. Investors:
Use hardware wallets (Ledger, Trezor) to store assets securely
Enable two-factor authentication (2FA) on all exchange accounts
Avoid platforms offering unregistered securities or high fixed returns
Maintain transaction records for IRS Form 8949 and Schedule D filing

What are crypto scams, and how to avoid them?
Crypto scams are fraudulent schemes designed to steal digital assets through fake platforms, impersonation, phishing, or deceptive smart contracts. You can avoid them by verifying sources, using secure wallets, and avoiding offers that promise guaranteed returns.
Cryptocurrency scams target users by exploiting anonymity, irreversible transactions, and lack of oversight. According to the Federal Trade Commission (FTC), U.S. consumers lost over $1 billion to crypto fraud between 2021 and 2023. Scams range from fake investment platforms to phishing links and social media impersonations.
Common Types of Cryptocurrency Scams:
Phishing Attacks:
Fake websites or emails that steal private keys or seed phrases
Often mimic real platforms like MetaMask, Coinbase, or Binance
Rug Pulls:
Developers launch a token or DeFi project, attract liquidity, then disappear
Common on unregulated platforms like DEXTools, PancakeSwap, or Telegram groups
Ponzi or MLM Schemes:
Require users to recruit new investors to earn profits
Examples include BitConnect and Forsage, both shut down by regulators
Impersonation Scams:
Fake social media profiles of celebrities, CEOs, or crypto influencers
Promises of giveaways requiring users to "send crypto first"
Fake Airdrops & Token Drops:
Users receive free tokens that link to malicious smart contracts
Signing the transaction can drain wallet funds
Pump-and-Dump Schemes:
Low-cap tokens are artificially inflated by coordinated buying
Insiders sell at the peak, leaving others with worthless tokens
Fake Wallet Apps:
Malicious mobile apps that harvest seed phrases upon setup
Often found in unverified app stores or scam browser extensions
How to Avoid Crypto Scams:
Never share your seed phrase or private keys with anyone
Verify website URLs before connecting your wallet—use HTTPS and bookmark official domains
Use hardware wallets (e.g. Ledger, Trezor) for storing large balances
Ignore messages from unsolicited accounts on Twitter, Telegram, or Discord
Avoid any investment promising “guaranteed returns”, fixed interest, or risk-free profits
Check token legitimacy via CoinGecko, CoinMarketCap, or Etherscan
Use browser wallet features like “contract simulation” (e.g. on Rabby, Taho) to preview transactions
Stick to audited DeFi protocols and check for security badges from firms like CertiK
Regulatory Resources for U.S. Users:
FTC Scam Tracker: https://reportfraud.ftc.gov/
SEC Investor Alerts: Scams involving unregistered ICOs and Ponzi tokens
CFTC Whistleblower Program: Reports of market manipulation or illegal derivatives
IRS CI Division: Tracks illicit crypto tax evasion and theft
Crypto scams thrive on misinformation, urgency, and technical complexity. Avoid them by staying sceptical, securing your assets, verifying everything, and using regulated platforms. If it sounds too good to be true—it’s likely a scam.
What are the rules and regulations on cryptocurrency?
Cryptocurrency is regulated through a combination of federal, state, and international laws that govern its classification, taxation, trading, custody, and anti-money laundering compliance.
There is no single unified crypto law in most jurisdictions. Instead, governments apply existing financial, tax, securities, and commodities laws to regulate cryptocurrency use, trading, and business operations. Regulation differs by country and depends on the asset type (e.g. coin, token, stablecoin), activity (e.g. trading, lending, staking), and the entities involved (e.g. exchanges, custodians, investors).

What are tokens in cryptocurrency?
Tokens are blockchain-based digital units of value created on existing networks, used to represent assets, access rights, or utility within decentralised applications.
Unlike coins like Bitcoin or Ethereum, which run on their own native blockchains, tokens are built on top of established platforms—most commonly Ethereum, using standards like ERC-20 or ERC-721. Tokens are governed by smart contracts, making them programmable and interoperable across decentralised systems.
Main Types of Tokens:
Utility Tokens:
Provide access to products or services within a platform
Example: Chainlink (LINK) for oracle services, Filecoin (FIL) for storage
Often used to pay network fees or incentivise participation
Governance Tokens:
Grant holders voting rights in decentralised protocols
Example: Uniswap (UNI), Aave (AAVE), Compound (COMP)
Used in Decentralised Autonomous Organisations (DAOs) to make protocol-level decisions
Security Tokens:
Represent ownership of regulated financial assets (e.g. equity, debt, real estate)
Subject to securities laws (e.g. Reg D, Reg S) in the U.S.
Examples: tokenised stock offerings, asset-backed debt instruments
Stablecoins (Tokenised Fiat):
Pegged to fiat currencies like USD
Example: USDC, USDT, DAI
Used for trading pairs, payments, and DeFi collateral
Non-Fungible Tokens (NFTs):
Represent unique, indivisible digital assets
Example: Digital art (CryptoPunks), domain names (ENS), identity credentials
Use ERC-721 or ERC-1155 token standards
Technical and Legal Attributes:
Tokens are created using smart contracts, not mined
Stored in wallets and traded via decentralised exchanges (DEXs) or centralised exchanges (CEXs)
In the U.S., tokens may be regulated by the SEC, CFTC, and IRS, depending on function and issuance
Tokens are programmable digital units built on blockchain platforms. They serve distinct roles—from powering decentralised applications to representing ownership, governance, or value—and are central to the operation of modern Web3 ecosystems.
