Exchanges are not a Banks, never never leave on exchanges more than you can afford to lose
Exchanges can be hacked, or run out of business, or like cryptobridge asking now for kyc.
By the way this requirement only for US citizens, if you want to withdraw, just use a VPN or Proxy

Update:
Only bad thing is right now, api only connect to US nodes, EU nodes seems down.
If you want to change them, you cant. This is very strange, they are forcing all users go through KYC requirements
