You were experimenting with sports betting and found yourself profitable with your strategy. However, you can’t raise a bigger bankroll to generate larger profits. Then there’s this one guy who believes in you and is willing to lend you money, of course, with interest, almost like a loan shark rate. The question is, would you see this as an opportunity or just a trap?
If the guy that wants to offer me the loan truly believes in me and my skill, then he should take a share in the risk. To take a share of the risk, he should not loan me the money but rather give it to me as an investment so that any profit we make will be shared between us and if I lose the money too, I would not have to pay him back. If he doesn't want it like that, then he can give me the money on a zero interest, because I can not take an interest loan to gamble.
