KYC or Know your customer is not kilking crypto. I don't see anything bad or negative about this. This KYC is for protection for anti money laundering and scammers. If this way will keep me safe, i'll accept it.
If an exchange is asking for your private documents they have the responsibility to keep your identity secure and how are you sure that they are keeping it safely in the context where you are hearing exchanges being hacked and loosing their coins, how what guarantee is there that they will be protecting your documents when they cant even protect the coins they are holding, we need to have a combination of everything and you cannot run a business without following the rules and so exchanges are forced to ask for the documentations.
