A time capsule with a 1TB HDD, but if the wallet reaches 700GB I will probably have to pull it out of the ground and meditate if the Universe wants me to sell or put it in a crypto with a wallet that is like 3 < > 30 GB max for now or then.
You can always pull the key(s) (you do have backups anyway, right) and import them into a non-node wallet (you're not actually running one at the moment anyway). Or just turn them into paper wallets.
Yep... I know I can claim the key to another 2 Terabyte HDD.. But the 'turn the key into a QR code' for the paper wallet, that could work too, but I'l need to research how to do that.
