Important risk warning
Cryptocurrency is highly speculative. Bitcoin dropped 77% from its 2021 peak. Never invest money you can't afford to lose entirely. Most financial advisors recommend keeping crypto to 5% or less of your total portfolio. Understand what you own before buying.

Self-custody vs. exchange custody
Keeping crypto on an exchange means trusting that company with your assets (see: FTX collapse 2022). For amounts over $1,000, consider a hardware wallet (Ledger, Trezor) for true self-custody. 'Not your keys, not your coins.'
| Exchange | Spot Fee | Coins | Security | Best For |
|---|---|---|---|---|
| Coinbase | 0.5-1.5% spread | 200+ | Insured custodial | Absolute beginners |
| Coinbase Advanced | 0.05-0.60% | 200+ | Same as Coinbase | Reducing fees |
| Kraken | 0.26% taker | 200+ | Never hacked | Security-first |
| Gemini | 0.5-1.5% spread | 100+ | NY charter | Most regulated |
