Since, it is "freebitco.in" people sometimes think about this place as a way to make free bitcoin. I mean I do understand the logic, at first, I considered it that way as well, I didn't see this as a casino at all. For me this place was a place to get free bitcoins (satoshis) and as a side thing they also had a casino implemented as well, not a casino by heart but a faucet by heart at first. Then I realized that wouldn't work as a business, you guys would have been bankrupt long time ago if that was the case.
This is why now I do understand why you do certain things but that is of course because I understand the point of view right now, some people may still not understand it.
I'm an enthusiast of this site because besides keeping legit along so many years, they are unique. It's the only site as far as I know that offers 3 main features to supply 3 different kinds of customers: gamblers, investors and faucet users. And you aren't forced to use one feature to have access to another. You can just use it in the way you want. That is great!
And even among faucets freebitco.in is the best so far, because they still pay rewards in satoshis and not in "coins" like another sites of the same kind, so you have to accumulate, let's say, 1000 coins to exchange it for 1 satoshi unit, what is terribly frustrating and hard to calculate how much you are earning for real. Moreover, they are probably the highest paying one if we count on the free wheel daily spin received through email, which rewards 40-45 satoshis really often. Probably only cointiply site could be considered a competitor on this matter, although they also pay rewards in "coins", which keeps devaluating your balance in case btc rises in price.
To add here, aside from free satoshis, you are earning also free lottery tickets and RPs.
Which you can already participate in the lottery as well as convert your RPs to bonuses like WoF, free btc bonus, & other RP prizes.
For sure, these features won't survive if freebitco itself is not generating income from other features like their betting and multiply btc.
And one major attraction also is their win a lambo contest. If you calculate that amount of GTs bought to the corresponding price, you will see that they already got a very good profit.
That is, without considering the GTs generated via wagering or playing.
