I have an ideea for easy money making
It involves races, and betting, and a friend.
Probably you should make just a really really small race, so it doesn't take long, or use Criminal Records.
You need 2500$ at least in cash. Bet on yourself, then win the race, your friend has to let you win it.
Then replay, and/or switch roles, who wins.
Anyone wanna try and confirm it?
