While autism is no laughing matter, I don't think cryptocurrency is the best means for developing money skills. A game of monolopy? Perhaps. Or just... regular math.
"You buy a loaf of bread for $1.46, lunch meat for $2.84 and some sliced cheese for $2.13. Add a 7% sales-tax and figure out how much change you get back if you pay the cashier with a $20 bill"
That's learning money skills.
Or balancing a checkbook, or making up a budget to get through the month on a fixed income, etc.
