Crypto's real question was never how transactions settle: changing the currency is something that happens to retired people who have no way of making new money.

There have been countries that have gone through currency resets. This is not a nice experience because if you had a little bit of money, a currency reset can mean you have now no money. If you had no money, it may feel like it's impossible to ever get any more money. If you're retired, what do you do during a currency reset?
