1. Exchanges: Where You Buy and Sell Crypto
Think of them as brokerages for stocks. The biggest globally: Binance, OKX, Coinbase. You register, deposit, and trade there. Choosing an exchange takes some care — see our exchange comparison.
2. Wallets: Tools That Hold Your Crypto
Strictly speaking, coins in your exchange account are “held for you by the exchange.” A real wallet (like the OKX Web3 wallet or MetaMask) means you hold the private keys yourself. Keeping funds on an exchange is fine at first; learn wallets as you level up.
3. USDT: Crypto’s “Dollar”
USDT is a stablecoin — 1 USDT ≈ 1 USD, with a nearly fixed price. Beginners usually buy USDT first, then use it to buy BTC, ETH, and other coins. It’s crypto’s medium of exchange.
4. KYC: Identity Verification
Know Your Customer. Exchanges require you to upload a government ID plus facial recognition — the same logic as opening a brokerage account. You can’t trade without passing KYC. See the KYC tutorial for details.
5. Trading Fees: Paid on Every Trade
Spot and futures trades all pay fees to the exchange. Fee levels directly affect long-term returns, which is why rebates matter — they give you 20% of fees back. See how rebates work.
