Someone I know was hacked one time. But it is because he accidently sent his private key and they took all of his token and eth, and in this post, I see that many people encounter the same situation, to me, i bought a hardware wallet, Trezor, to keep my assset from hacker. And I think it worth to do it
My friend also foolishly sent his private key instead of the address. Before he realized his mistake, how all his means were stolen. This is mainly due to people's inattention. And Tresor is really a good idea!
