I'm not a bitcoin person, but I kind of get the logic there. If you had two stashes, one of money that was going to be worth more in the future and one of money that was going to be worth less in the future, wouldn't you take from the stash that was going to be worth less to spend on household things? I guess you could spend the money that was going to be worth less to buy some money that was going to be worth more, and then immediately spend the money that was going to be worth more (before it *is* worth more) on household things—but then isn't that just adding steps and fees?
