That doesn't mean you can't use a NO-KYC wallet(non custodial), using a NO-KYC wallet can still allow people to know your balance but that's if you are willing to connect your identity to it and can be done in several ways you like even announcing it

.
Having (non-)KYC coins and (non-)custodial wallets are two different things, and one doesn't necessarily imply the other.
KYC means there's a link between your identity and the coins you own (most of the time because of the paperwork you have to do to use centralized exchanges).
Custodial means you rely on a trusted third party to hold the coins for you.
I know! and most BTC Identify with KYC are mostly from custodial wallets , that was why I added in the bracket to show that I'm talking in term of wallet .....
