Yeah I've heard it around me there's like that, someone lends money to his friend to gamble, then will promise more money back when getting the benefit of his gambling. If you asked a friend to fund gambling he'd better just ignore it, because no one guarantees a 100% win in gambling, if he always wins in Gambling he should never lack money.
yep, that's right mate. If he is a professional gambler who always makes a profit every day, there is no way he will borrow money to gamble.
sometimes we have to be careful in gambling and we have to be smarter people in this matter because there are many cases like someone who has just entered a casino has no friends and is welcomed by strangers and over a long period of time they become friends and in the long run long the person will borrow money to gamble and the approach will only want to use the money.
in this case we dont have to give a loan to a friend just to gamble unless he borrows for something else and rather than lending to an unknown friend and just relying on luck it is better as @kamvreto said funding professional gamblers and my suggestion is to choose funding professional gamblers who betting on types of bets that rely on skill such as poker. because with this your money will be a little safer and gamblers who are professionals at playing poker can definitely be relied on.
