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.
one dollars worth of a supermassive black hole please.
everyone is coming for the ride of their lives.
Hate to burst your bubble, but $1 worth of black hole would be so small, that it would likely evaporate before it did any damage to anything.

And if it really was $1 worth of time with the black hole, I doubt it would do any damage cause the gravity wouldn’t have time to do anything.
