So I think in these days you can't earn much from spins or from faucets. 
Free spin and faucets are not the same thing. I have used two faucets before which are freebitco and cointeply or so, you will solve captcha and earn bitcoin, but the amount earned is always small and not profitable than a waste of time. Free spin are different, as faucets are targeted on people generally, free spin may be targeted to some set of people which makes the difficulty of free spin to vary, you may earn nothing from free spin, you may earn something big from free spin, you may earn big amount of money from free spin.- You are right there Sir, but I just have a question, are usually free spins converted to literal fiat in gambling? or do you have to get the jackpot to make it fiat in their gambling games?
But with the other thing you said, I agree with the faucets, anyone who exploits it will just waste your time because even if you take this faucets system of theirs seriously, we still won't make good money in the faucets category of gambling platform. You can if you have nothing to do or you just want to have fun. There is a big difference between free spins and faucets.
