That’s a very informative post. Yes, hardware wallets are safe. They are more secure and no one can hack it. I personally love using hardware wallets.
What kind of hardware wallet are you using? I am thinking about buying one, but can't decide between Ledger and Trezor. Ledger seems a bit more attractive to me, but I am open to any new suggestions.
Ledger Nano S user here, since I've got it I've had no problems at all and it's worked like a charm - no regrets at all.
However, if you are the paranoid type who wants maximum-overdrive-security, I'd actually recommend the Trezor as they seem to take bug reports a lot more seriously and are quicker to respond to them, also with Ledger you have to make do with Chrome apps to access your funds whilst with Trezor they are moving away (or have moved away?) to using Trezor Bridge.
But seriously, in the end you cannot go wrong with either. But I would said that Trezor has like a 1% lead over Ledger right now.
