My bitcoin wallet has not been hacked. It exists in a cold wallet.
As long as you don't disclose your private key to others, hackers can't invade.
I still believe in the security protection of bitcoin.

Even if you do not give out your private carelessly, simply making silly mistake by connecting your network to phishing WiFi results to the lost of your bitcoin by scammers who search in your device looking for your private keys, so you can win the hackers by storing your funds offline as this is the best way of keeping your secret keys.
