Frequently Asked Questions
Should I keep crypto on an exchange or in a wallet?
For active trading, keep small amounts on exchange. For long-term storage, move to a hardware wallet. Never keep large holdings on an exchange (FTX, Celsius examples).
Can I trade directly from a wallet?
Yes, via DEXs like Uniswap. But for high-volume trading, exchanges offer better liquidity and order types.
