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?
Borrowing money to gamble is never an opportunity, despite how far you might claimed to have been successful in the past, because to be frankly speaking, it is actually a trap, and I wouldn't advise anybody close to me to see such scenario as an opportunity. Because the truth of the fact is that while gambling, you literally have no control over your bet, and as such you stand a 50/50% chance to win or lose, but a higher chances of losing, due to the fact that casino always has a higher advantage over gamblers, most especially on luck based games. Hence, the best decision to make is to tell the guy if he is willing to risk his money, then you gamble and share the profit. Both if you lose, you both bear the lose.
