I would try investing in something that seems reliable.

"If you're a homeless person and watching this, donate only $20 to my church and I pray so hard for you that by the grace of God you'll get your own house in a couple of weeks. Amen."

Buy a cardboard box.

Lol… you’re funny, Daniel.

Take an Uber to the nearest bridge and jump off ?

it should be easy since most new citizens arrived without a penny and all became millionaires soon enough.

Buy some things and sell them for double the price until I manage to rent a room.

Other than spend the $20 on a jackpot winning lottery ticket (which is never going to happen), it’s get yourself put in jail, like Sean said.

You can't even put a hit out on yourself for that. I was going to say you could just spend the $20 on something, and then go out and exist as an unhoused person and probably et arrested and become housed in jail. But when the cops show up you may also just be killed, so you know.

commit a crime and go to jail, we are more than happy to pay for that - there is nothing $20 can do that would put a roof over your head
