I started learning about crypto in 2017 bull market when BTC was at $10k... then dove into the wallets to learn which one was the safest and back then, every wallet had flaws, talking about ones that we hold the keys. From desktop softwares, web wallets, mobile apps, all expose keys on screen, which hackers can get access to. Highly unlikely to get your stuff stolen or hacked but not impossible. Ok for small amounts and convenience. Paper wallets has the disadvantage of inconvenience, if someone steals your paper wallet you lost. if a tornado destroys your home you might lose it too. If the feds invade your home and throw you in jail, confiscate and shred all your belongings you lost it. If you get thrown in a concentration camp for being unvaxed you lost again. If you get deported from a country like some of my friends have, the imigration kept all their eletronics and belongings. Lost it all, never allowed here again. Also keys exposed on screen on paper wallet even if offline, and keys exposed through printer also. Once I read a story on people going through printers in landfill trying to restore private keys from paper wallets that had been printed on them. Paper wallets are pretty safe, you will highly unlikely lose your coins, but its technically possible. If someone knows you have crypto you get your home broken into and printer stolen, you lost again. Hardware wallet however, Trezor, Ledger, etc. buy it, it generates your keys in the device 100% cold stored, grab your public address and use it. Memorize your words, dont write them anywhere at all, or if you do write them down on a paper for 21 days to memorize it, make sure you burn it afterwards. Reset your device to factory and thats the safest way IMHO. There is literally no way anyone could ever have access to your keys except at gunpoint. Need to use your crypto? Punch your words in your device, use it, and reset it again. That's it!
