So that means that the restriction not just applies to sending dollars to your bank account, but also to any other crypto wallet?

So if I have 30 BTC, I won't be able to send all the 30 BTC to another bitcoin address?

Please clarify this.

Thanks.

Hi,

I'd like to start trading on POLONIEX. Let say I transfer 10 BTC from my local wallet to POLONIEX exchange wallet. I start trading and after a month I end up with 30 BTC (10 + 20 out of trading profits).
Can I just send those 30 BTC back my local wallet without any kind of KYC? Or do crypto withdrawals require some sort of KYC as well?

Also, is there any crypto trading limits? Or as long as everything remains on crypto, I can trade whatever I want?

Are these rules apply to all exchanges?
Is there any comparison table of exchanges in regard to these features?

Thanks.
