How will you feel if someone you know or just a friend of a friend walk up to you and ask you to finance them in gambling in exchange for a portion of their winnings? Does this even make any sense?
Nothing make sense in the world of gambling to be honest with you. Everyone play, become addicted, or have some fun, but still they are going to lose money in the end. And so if someone approaches me with that kind of proposal, I wouldn't accept it. I will try to reason out that it's not a good thing to do and besides I don't have money or extra in my pocket.
Just make sure that you explain it in a nice way and don't be rude as he might take it negative. And if ever I had the money, I still wouldn't lend some even if the proposal is good, like I will have the big percentage of the cut, but still though, he will not shell out money and you will, and then the risk involved. We all know that in gambling, no one is going to win in the end.
It does not really make any sense, because even if we were to give the benefit of the doubt to the friend and assume they can do exactly what they claim, at the end the one taking all the risk is yourself, since you are the one forking the money for this supposed business opportunity.
And obviously you do not need to be a genius to know this is a terrible proposal, because if that friend lost your money then they will not reimburse your losses, and if anything they may try to convince you to spend more money so they can recover the money they have lost already.
That's what trust could lead to. If you trust a person to succeed in gambling, you'll risk your money without questioning him much, given that you know his credentials. If he loses, then it's up to you whether you are still willing to finance him to see if he'll end up profitable. Though this is quite risky, being a gambler already considers ourselves to be risk-takers, so we decide whether we are willing to experiment on this to improve our profitability.
It's just a matter of success and failure; once it fails, you won't finance again. But if the person is winning, that would help you earn consistent profit, provided he sticks with the same setup.
