D&D has too many rules. I invented a really light weight set of rules so that we can engage in more "role play" as opposed to RTS. It's more fun for the casual game and you don't waste so much time between turns.
Turns out nobody is actually interested in transacting with crypto otherwise Nano would have been a winner. I also love Banano, a Nano fork where you mine by folding proteins. Work that has actual value.
The other option would be to rebase the currency such that a single penny was a meaningful unit of money again. One potential such way would be to issue new paper notes which represent the old note with a decimal place move such that $10 becomes $100. This has been done before but might not be a great idea for the USA.
