I don't know why so many people say Coinbase, you know it only serves probably the most limited of all exchanges? That means more than half of this forum can't even use them.
If Binance is available at your place then, it’s the perfect place to trade. It has good user interface and the almost all the coins are listed here. 9 out of 10 customers use Binance and it’s very famous for its quick user interface.
Binance is almost available everywhere until recently and IMO still the one that majority can access.
Always hated Binance but can't deny it's the most useful for newbies in most countries. Don't know about 9 out of 10 but it's the biggest exchange for a reason.
