Armory allows you to create a deterministic wallet. This is a wallet where all the other addresses that will ever exist are based on an initial secret seed, so it is sufficient to create a backup of only this seed.
+1 Thanks for explaining. Seems like I need to convert and start depending on one of the deterministic types but doesn't this always require some additional software or supplier when thinking about long-term storage? For example if Armory doesn't exist anymore in 2023 who is going to recover/recreate my wallet?
This would leave the option to use single "receiving one transaction only" paper wallets? My only concern is staying future-proof and independent as possible. Not disregarding the various tools but there are no guarantees to stay around for years to come.
