If you ask my that question before one year, than definitely, i will say Yes, i did play gambling only for profit. But now, i have learn many things from gambling, First, it is not necessary, that we always win in it, and Secondly, gambling is a game, and also in that game, It is same like other games, result depend on win or lose, So doesn't matter if we lose. Because may be in the next step we win a big amount. So always play gambling with a new hope, and play not only for profit, should play for fun.
I think miss the question what OP asking above read it again he is asking do you play with your profit or not, because gambling is for only profit almost impossible any time we can lose against any losing streak because nobody knows what will be happen next, I want to make my money and will take withdraw after make the profit if possible for me.
