- Hardware wallets : An excellent way to store coins, private keys are always stored inside the device, for me best option.
- Paper wallets : Good choice for long term storage, need to be created in safe environment/paper need to be stored in safe place (fire, water, etc..)
This is where I am coming from. I've heard several people say that paper wallets are the safest or most secure option. I suppose they are the least hackable since they are not electronic - but don't they run a higher risk of accidental destruction (whether by fire or water damage)? I use a Trezor and have my recovery seed stored in a padlocked steel wallet, covered in vacuum sealed plastic.
