I think that's a different platform. He's talking about blockchain non-custodial wallet I suppose, not the centralized exchange. You don't need any KYC if you use their wallet, but it's buggy af. I suggest OP to export his private key and use another wallet.
But in case OP doesnt know how to export private keys to another wallet. He may further do two things in a simple ways;
- Just transfer funds to another wallet (freewallet, tokenomy etc. Where in he can exchange coins without problems of limits)
- Exchange not too much funds cut it into half or in a $100 for exchange coins everyday, he may try that as an alternative.
I don't also think it may required documents for him to exchange coins.
