Kucoin o Coinbase supports xyo or chsb?
XYO trades on both exchanges. They don't seem to support CSHB. Please note if you are planning to withdraw ETH, you are going to spend ridiculous amounts in withdrawal fees that those exchanges set. For example on Kucoin, withdrawal fee is 0.005 ETH (~ $20)
They need KYC to use it?
Yes they do.
