It's a shame if you think like this. I slightly disagree with you. Indeed, there are several cases that have made some data on KYC spread to irresponsible people. But I think not all even exchange though. They do KYC because it is a procedure. If we don't want KYC then don't register. Even at the bank you have also submitted paper documents, that also includes KYC. They seek security for the continuity of their business, so they must know our data, with guaranteed confidentiality. It's a shame some exchanges don't have KYC but have a smaller limit when withdrawing money.
