Himself and some other friends are those I do not want them to miss out in bitcoin investment, a reason I every time took my time to explain and any beginners may learn from this short response.
1- You bitcoin address in not your bitcoin but a house for it just like your bank account.
2- Your bitcoin address can only be be compromised if you share your personal details or private key along with sharing the address.
3- People may say that your bitcoin address can be likened to your bank account and and email address, I have read it online myself. They are right to some extent, but the privacy of bitcoin is far better. Why? Through your bank details, your details can be known by diggers, same goes for email address if you use your real identity to open it.
But for bitcoin, nothing will be revealed relating to you by merely seeing your address. It is again good to use non-custodial wallet for keeping your bitcoin safe and own total right to it.
Yes, but you should know that it's only addresses, it doesn't have any name on it. Specially if you exposed a wallet addresses that you have control of, then I doubt that someone will know that it belongs to you unless you publicly going to state it that it is yours.
Of course, there is blockchain analysis that can track your addresses, but they really need to dig deeper and to see the connections per se.
And this is why there are traders who like to used DEX, because the exchanges doesn't require you to submit KYC and again, you have that control of your private keys which is very important.
