If you have plans to do margin trading, then there are exchanges that would allow you to trade on their platform without having to do KYC. Although your activities on some of these exchanges might be limited, such as your amount that you can deposit and withdraw. And another thing is that it depends on the country that you are staying. For margin trading, I am going to recommend that you choose Bybit exchange.

This exchange is really a good exchange and features advanced tools, and it allows its users to trade without having to do any form of KYC.

But, it doesn’t allow U.S. citizens on its platform. So if you are in the US, this is not an option. Maybe you can look at Nominex exchange, it is another good exchange, but your withdrawal and deposit would be limited to three BTC in a day. Finally I’m also going to recommend binance.com, which is already a popular exchange, and they allow you to trade without KYC to an extent. Try to do your own research still and see what you can come up with.
