Every time you get in a car you take a risk. Doesn't mean you should drive with your eyes closed.
but if you have risked too many times, it will become a habit, and you will no longer feel so afraid, until disaster strikes. If KYC becomes a habit when using centralized exchanges, many people will probably do KYC everywhere, which is a really dangerous thing.You won't be saying that when your identity is stolen and you end up on the hook for $50,000 in debt and credit cards you didn't open. You won't be saying that when someone links your identity to being an active bitcoin trader and shows up at your house to steal your bitcoin. KYC is always a risk.
he won't be afraid until he encounters something bad from his identity being revealed, those who don't know will never be afraid 
You have absolutely no idea where your information ends up and who has access to it after you complete KYC.
I think we have a simulation process. we do KYC, identity is revealed on that platform, then it is passed to a third party for verification, third party will probably store it in some cloud, cloud data providers may use and analyze such data for their own purposes, eventually, data in the cloud can be leaked or hacked, it is moved to a new side, and a new loop can start. Up to 3 different parties capture our identity before it moves to the new round, and we don't know how many rounds our identity will be moved. In short, it's extremely dangerous!Not correct. I have never completed KYC and I trade between fiat and bitcoin regularly via peer to peer trades on platforms like Bisq.
great that you have a good P2P platform to use, where I live P2P platforms still require KYC for buyers
