I think this will be the best thing you can do with your profits. People dont have even this knowledge in gambling that playing with your capital can put your life in danger in future as well as his relatives. This is only good when you are unable to forget gambling. If you have some self control on you, I think quitting gambling and going for trading with your profit is better thing than continuing gambling with that.
I think smart gamblers do the same thing that is they play with their profits and the real amount they save so that they can deal with future financial crisis situations. People who start playing with their capitals are always facing financial crisis because they didnt have a little bit common sense that playing with capital id dangerous as it is bigger amount while profits are smaller and they cant help you to tackle situations as this will do.
As a person who does not like gambling, I'll try to answer. I will choose to use profit from gambling to build another business. I will not gamble constantly, because after all, gambling is not good and can make us lose. If you're rich, then it will not matter. Besides, I also do not like to risk my money on something that is not certain and I also do not like to take risks. I prefer to learn something and do things gradually but certain. But to realize it maybe we should be very lucky so we can win a lot of money. But rather than risking our time and money to find a big profit, I better use my money and time to find a real job and build real business.
