Universal money and Anonymous is the biggest strength of btc BTC, now every country follows KYC and then it can be controlled by someone.
Now KYC is trend in crypto market.....
The exchange like a Bank so it requires KYC form. The Bank uses the identity to be safe and no fraud. Exchanges strive to protect users and investors so that they can be protected from fraud and money laundering.
But what I sometimes also appears fear because every exchange, of course, is not the same about security issues. Sometimes the confidentiality of our documents can be leaked, when getting false exchanges.
KYC actually has a good impact and some exchanges are very secure.
