/biz/ what are your cold storage options? Sure we can write a seed or private key on paper. But what bout nice cold digital storage so I can copy and paste shit instead of reading off paper?

Use CD-Rs, these cheap old medias can still last 50-100+ years if kept in good conditions and rarely used. CD-Rs are better then flash storage like USBs that can slowly deteriorate overtime and since storing crypto keys dont require much space, 700MB CD's are perfect.

Or buy a fucking trezor

Bonus points if you store data on blu-ray since those discs can retain data for 10,000 years, but by then nobody will have the means to access that data. You'll need to keep a old PC and blu-ray reader in a box somewhere.

Setup an air-gapped computer that has never touched the internet. de-solder or disconnect any wireless internal antennas or network cards. setup linux but compile everything from source code yourself, and audit all source code first. setup a paper wallet generator using a cryptographically secure source of random entropy.

transfer your BTC to the public key address you generated offline for your paper wallet. now your coins are safely stored offline and can't be hacked. the next step is critically important. take your paper wallet with BTC on it, and the next time you feel the call of nature, wipe your ass with that paper wallet and flush it down the toilet because that shit is worthless.
