That's not a good idea, if you are investing on your bank roll, but if you are an investor in side with the house then that's a great idea, you will earn bigger with that.. Just make sure not to gamble your profit from your investment..
It is choice to gamble what we have but to be sort all thing of hes doing good their since he limit only hes lose so by that he can really avoid losing big and to be addicted for the certain gambling site where he plays gamblin. And for me literally i limit also my self to 10% capital lose or win and dont comeback to gamble this day if i reach that 10% limitation, so by that doing i can dicipline my self not to spend more time and lose all what i got from it.
