The dollar can be used once a day. It has to be a dollar’s worth of a product, service or use of a product. For example, A dollar’s worth of a $100 TV would be the life of the TV divided by 100. You would get to enjoy the TV for that amount of time. The product or service is instant and doesn’t require any preparation. It just appears and disappears. Or you could have a TV permanently that is worth one dollar.
If you choose, you can time travel to the ‘distance’ in time worth one dollar, however much that may be. There is also no rule against saving.
So I can travel back in time 8.27 minutes? Because that’s what a dollar is worth according to the US Federal Minimum wage.
Cool, I guess I can save up a year worth of magic dollars then I can go back in time 50 hours.
Not bad for a passive income.
Choose any stock or crypto that went up by a lot in the last 8min, travel back, buy all your moneys worth and sell 8min later. Repeat every day
‘buy’ a dollar of someone’s time, kill 'em, then automatically teleport out and back to safety and alibis.
