I usually use Binance for trade but i have also experience about Coinbase, Bittrex too. Every exchange have their own specialty although i never thought that Coinbase is better than Binance. For beginner i would like to recommend to start their trade with CEX exchanges like Binance, Kucoin cause DEX exchanges are more complicated use than CEX. No doubt that coinbase is trustful exchange but there is not much special about coinbase it's just hype nothing else. Most people like because of there affiliate program for new sign up users.
