Just purely out of curiosity. 99% of people who don't know how to properly create an airgapped device should be using hardware wallets.
Hardware wallets also have their drawbacks.
Hardware wallet software may not be perfect. Developers and testers can make a mistake in their work, as a result of which your funds that you store using hardware wallets can be stolen.
To buy a hardware wallet, you need to make an official money transaction using fiat currency. Disclosing the purchase of a hardware wallet will also put your financial security in question. In addition, your hardware wallet can be misused while being sent by mail.
In addition, the very fact that you have a Ledger or Trezor indicates that you have a cryptocurrency. This information can be used by attackers.
