1. From your experience which of the trading platform has great features and epic user experience (UX) that new traders should learn to use.
2. What is special about coinbase that almost all the website are ranking it to be the best crypto trading platform?
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.
I also make use of Binance more than any other crypto exchange, probably because it has one of the most friendly UI and its one of the biggest crypto exchanges, the only reason why I make use of other exchanges is because of bounties, not all bounty projects are able to list on Binance, but after changing the token to usdt or trx I normally send it to Binance and trade there, I'm not a fan of coinbase due to their kyc restrictions, so have been avoiding it as much as possible.
