Know your customer, the onus is on the customer to prove themselves a legal entity in order retain possession of their crypto at various sites like exchanges. Its seen by some as a form of exit scam as its often used as a play after value is placed in an account. I've had that done to me by a company that disappeared, they had my driving license but asked for further evidence before closing the site and retaining all account balances. Thats the risk a customer is asked to take currently unfortunately.
At present I'm having an exchange tell me after verifying my identity and photo, etc. 2 years later I no longer qualify as a valid person and once again the account funds are theirs to use as they wish indefinitely until I prove otherwise. Its not really a fair process and the industry has no standardised proper process so it is used as a scam by some and profitable process by others.
The KYC I've encountered in crypto far out weighs the red tape any real bank has leveraged against me and there was never any threat to retain my funds during that process.
Due to anonymity then this is the reason why these fraudsters can really sip out hell of a lot of these documents yet they can easily flee away without being traced and tracking them would be really a pain in the ass
thats why when we do talk KYC then its highly frowned upon on this crypto market but we know that the platforms that we used specially the known ones are really complying government regulation which there would be no options if once you've been asked for such verification.
It sucks but we cant do anything about it but somehow there are platforms that do made KYC as an optional for you to comply which is great.I hate KYC but there would be surely some scenario that they would ask on it from a certain time.
Here on crypto, we do love being anonymous and these KYC things is highly contrary to that.
