for the newbie,they dont need to be afaid in kyc and I don't think the account block will happen as long as they don't do fraud.
in my opinion all wallet is not safe it just depend how you use it
You are continuing to give out bad advice.
Everyone should be afraid of KYC every time you have to complete it. You are sending everything required to completely steal your identity over the internet to an anonymous bunch of strangers. Identity theft can do more damage to you than someone emptying your bank account, and you can be left with life long implications, poor credit, debt, even criminal charges.
Saying "all wallets are not safe" is equally poor advice. Sure, there is no such thing as a 100% secure wallet, but that does not make the security of an encrypted airgapped cold storage wallet equal to that of a third party custodial web wallet.
There is a big difference between making things simple and oversimplifying things so much as to be dangerous.
