I trade on MEXC — one of the largest cryptocurrency exchanges in the world. Pros: a wide selection of trading pairs (over 1500), low fees (0% on spot), good liquidity. There is the option for futures trading, staking, and stocks. The interface is user-friendly and mobile-friendly. Customer support is available 24/7. As for the cons: some altcoins can be risky, so caution is required. I recommend it.
