  • Decentralized: Not controlled by any government or central authority
  • Transparent: All transactions recorded on public blockchain
  • Secure: Cryptographic protection makes counterfeiting nearly impossible
  • Borderless: Can be sent anywhere in the world instantly

  2. Ethereum (ETH): Smart contract platform, powers DeFi
  3. Tether (USDT): Stablecoin pegged to USD
  4. BNB (Binance Coin): Exchange token for Binance
  5. Solana (SOL): High-speed blockchain for apps
  6. XRP (Ripple): Focused on cross-border payments

How Cryptocurrency Conversion Works

Converting cryptocurrency involves exchanging one digital asset for another or for fiat currency:

  • Crypto-to-Crypto: BTC → ETH, ETH → SOL
  • Crypto-to-Fiat: BTC → USD, ETH → EUR
  • Fiat-to-Crypto: USD → BTC, EUR → ETH

Types of Cryptocurrency Exchanges

1. Centralized Exchanges (CEX)

User-friendly platforms operated by companies:

  • Examples: Coinbase, Binance, Kraken
  • Pros: Easy to use, high liquidity, customer support
  • Cons: Require KYC verification, custodial (they hold your keys)
  • Fees: 0.1-0.5% per trade

2. Decentralized Exchanges (DEX)

Peer-to-peer trading without intermediaries:

  • Examples: Uniswap, PancakeSwap, SushiSwap
  • Pros: No KYC, non-custodial (you control keys), censorship-resistant
  • Cons: Steeper learning curve, lower liquidity for some pairs
  • Fees: 0.3% trade fee + blockchain gas fees

3. Peer-to-Peer (P2P) Platforms

Direct trading between individuals:

  • Examples: LocalBitcoins, Paxful
  • Pros: Privacy, multiple payment methods
  • Cons: Higher fees, scam risk, slower
  • Fees: 1-5% depending on payment method

Understanding Cryptocurrency Fees

Trading Fees

  • Spread: Difference between buy and sell price (0.5-2%)

Network Fees (Gas)

  • Bitcoin: $1-20 per transaction (varies with network congestion)
  • Ethereum: $5-100 (higher during network congestion)
  • Solana: $0.00025 per transaction
  • Polygon: $0.01-0.50 per transaction

Withdrawal Fees

  • CEX to external wallet: $5-25 (varies by cryptocurrency)
  • DEX: Only pay network gas fees

Security Best Practices

Wallet Security

  • Hardware Wallets: Ledger, Trezor for large amounts ($1,000+)
  • Software Wallets: MetaMask, Trust Wallet for daily use
  • Never Share Private Keys: Anyone with keys controls your funds
  • Enable 2FA: Two-factor authentication on all exchanges
  • Whitelist Addresses: Prevent unauthorized withdrawals

Avoid Common Scams

  • Phishing Sites: Always verify URL before entering credentials
  • Fake Support: Exchanges never ask for private keys
  • Ponzi Schemes: "Guaranteed returns" are always scams
  • Rug Pulls: Research new tokens before investing

Tax Implications

In most countries, cryptocurrency is taxable:

  • Capital Gains: Profit from selling crypto is taxable
  • Short-term vs Long-term: Holding > 1 year often gets lower rate
  • Trading is Taxable: Every crypto-to-crypto trade triggers tax event
  • Keep Records: Track all transactions for tax reporting
  • Use Tax Software: CoinTracker, Koinly automate calculations

Stablecoins: The Bridge Between Crypto and Fiat

Stablecoins maintain a 1:1 peg with fiat currencies:

  • USDC (USD Coin): Regulated, fully backed by reserves
  • DAI: Decentralized, backed by crypto collateral
  • BUSD (Binance USD): Regulated by NYDFS

Use Case: Convert volatile crypto to stablecoins to preserve value without exiting to fiat.
