Best crypto will depend on your criteria and preferences, and a platform that gives you comfort. You can check their reviews as well to have an idea of how they are performing but if I were you, I'd choose the top exchanges that have a huge trade volume as this has a significant impact when trading.

If you are looking for NONE-KYC, you'd better not expect that because the majority of them are now asking for it, if not during the registration, it can be possible during withdrawal.
