If you think you don't have the knowledge to create a paper wallet through an air-gapped device running tails, please, save yourself the headaches and just purchase a hardware wallet like a Ledger[1] or a Trezor[2]. People mostly think that just because a paper wallet is offline that they're already safe, even though a lot of people mess up the process by leaking the private keys while generating the wallet.
