Why do they say that? Correct me if I'm wrong. Isn't, hardware wallet, a hardware like usb, that generates private keys without being online on the internet?
Why do I not like them? Because, in addition with a txt file that you can encrypt with many ways and save it in many places, if your hardware stops working, you're a dead man. And you're going to fix it somewhere? Not that recommended. If you're a paranoid of course.
Prove me wrong, by not telling me the cons of software wallet. Prove me wrong, by telling me the pros of hardware wallet.
If your hardware stops working, there is an option where you can restore your wallet from the recovery phrase. Maybe you don't fully know hardware wallets that's why you don't like it or maybe you still don't get one to try if it is really the safest or not.
