is there a better secure method than a hard wallet like Ledger Nano S, or that is the best way to store crypto? there some people who have millions crypto do they also use only that method or they have a better method? with time could you balance be 100.000 $ or more so what to do to secure that?
Used correctly, hardware wallets present a very small attack surface. Someone would need to access the device physically to have any chance of stealing your privkey. Such physical access isn\’t trivial either – they\’d need to be very skilled to have any chance of extracting the privkey. So long as you keep the device secure and / or hidden, it\’s highly unlikely that your coins will be stolen. For maximum security, don\’t let anyone know that you even own coins (this can be difficult, as most people who are into Bitcoin like to talk about it).
There are other methods of storing your privkeys which can be equally or even more secure than a hardware wallet, however these are limited to experts in computer security. Maintaining an airgapped machine and immunizing it against various software and hardware-level attacks is best left to security experts.
I\’d say for the vast majority of crypto users, considering the price, convenience and security of hardware wallets, that they\’re definitely the best way to securely store and use coins.
