It definitely will make more people use their site but we shouldn’t forget that the era of faucets is over so anyone that wants to start earning from it now will only be wasting the time they would have spent in a more productive space.
Back then you could earn a significant amount from faucets but now what will 0.00000007BTC per hour do for someone? To me it’s still a waste of time to just rely on casino’s faucets entirely.
Well, I also agree that shady casinos tend to do things like that to attract new users only to make them deposit money on their sites. Most of those faucets are really created with such purpose only and the strange thing is that the people fall with such cheap traps. The main thing that makes those users to fall for such traps is the greed inside their hearts. Because of the greed of getting free money they fall for those offers as well that are noting but a way to trap those guys in the game of wager that they can't even think about.
You friend was also victim of such traps and finally he had to deposit more money only in order to fulfill the wager requirements, but I'm sure enough that he may finally ended up loosing everything he deposited in order to complete the wagering requirements. Well, wagering isn't a wrong model in casinos, but the shady casinos made wagering so hard that a user has less than 1% chance to complete such requirements.
