I think maybe it would be Profitable, if you never spend money on gambling, but you always play with the free money, so that when it wins it will be profitable and when defeat it's no problem.
Thats a clever decision or action of yours of using free money on playing gambling which is really a good thing if you dont want to risk your own money but as we all know making money with free money of faucets is really hard thing to do and you would really need luck in able to be profitable with it , faucets are just good for trials and so hard to make it as a source of profit. Gambling just do rely on luck does this mean it would really hard to make it as a profitable activity.
