I’d envision this to be like a matching program for your 401k at work. To encourage saving, it would be great to be able to say that for every 1000 sats the wallet receives, there is a certain percent that is then added automatically. If this is paired with a sending restriction (another feature suggestion), then a subaccount could be an excellent savings vehicle.

For example, if my son wants to get paid part in sats and part in dollars, then the sats would become even more valuable because there would be additional sats added in for the “match.”
