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?
You can use whatever money you like to gamble but a borrowed one is something I wouldn't advice anyone to do gamble with. The dangers involved in this are quite enormous considering the fact that gambling isn't really something that has a definite outcome and putting a sum of money that doesn't belong to you into it is absolutely ridiculous. If you end up losing the bet you are going to end up in debt
