You are right. I didn't even notice that before you made this post. I wonder why they have restricted to get the WoF spins to just 1 a day.
At least 10 - 20 spins a day would be so thrilling.
It's actually restricted based on how much you wager. If as I did in the old days you wager a lot you can exchange 100.
I'm sure you can guess why a casino would do that.
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.
