Just purely out of curiosity. 99% of people who don't know how to properly create an airgapped device should be using hardware wallets.
There are many reasons behind that people are not using hardware.wallet. And let me show you these,
1) First Of All All people are not aware of Hardware wallets like ledge nano wallet etc.
2) hardware wallets are not cheap and they cost some hundred bucks. And low volume users cannot afford to buy these wallets.
3) most people do not trust hardware wallets.
As you can see it ranges from 150 to 300 dollars and that's the reason mostly people do not know about this.
1) Mostly for beginners. It will take them some time to learn about the existence and purpose of hardware wallets. Only if they actively study the cryptocurrensy topic, and not just buy crypto and put it off for a long time.
2) If the investment in crypto is a couple of hundred dollars or a little more, then what's the point of buying a HW for at least $80 -150? Then already buy crypto for this amount.
3) Indeed, there is a category of crypto-enthusiasts who don't trust HW device manufacturers, and they are also able to organize the storage of their crypto in such a way that they don't need a hardware wallet. This is already the level of advanced users.
