Using gambling winnings to investing business that will be yield profits is a good way to use money to find money. We need to keep our money into action if we actually want to be making simple bets while we keep creating different investment opportunities for people around to work with us ....
making a business or reinvesting the gambling winnings is a wise and most correct thing to do; in that way one can expect continuous profit from it which can then be used again, whether for their needs or their gambling again. this method is better to do than just using their gambling winnings for consumptive things which can spend all the money they get.
It does sound like a good idea to invest your gambling proceeds in a business but the thing i always think about this is first how much is the amount won and then the sustainability of the business is another key and prime factor that you have to put to consideration while thinking of investing the gambling proceed in a business because after the investment, if its not profitable enough, you may still have to fallback to gambling which is something that may not be a good and healthy practice because at that point you may become desperate and may turn out an addict.
Yes, that's a good idea, because allocating the winning amount to investment is much better than you allocating it back to gambling, because after all investment is much better than gambling when it comes to the chance of profit, and I understand the concern that you think that someone should continue to gamble when their investment is not profitable, but I don't think it should be either, or I mean they don't always have to find money from gambling to then invest because after all it is clear that the risk in gambling is always part of the end of the game.
On the other hand, there is no compulsion or regulation either if for example you must always invest money from gambling results, meaning you can invest money from gambling results only when you win because it is much better than you use the money to gamble again.
