The premium membership they launched 2 years ago was a good move and especially in the very beginning, the WOF spins were very rewarding. I am also saving up my WOF spins right now (currently at 820) but just waiting until the price of BTC drops down so the base prize on the wheel will increase lol.
The betting is also nice on the site, not a lot of options but the pari mutuel betting is something unique and can be interesting.
Yes, the advantage is that if the price of bitcoin goes down, at least you get more satoshis, even though the value of fiat currency is not much different, the only difference is the number of satoshis you get, an increase in the price of bitcoin can also reduce all income from bitcoin free spins every hour as well as WOF spins, ideas which is fine if you have to wait for the price of bitcoin to fall before rotating all your WOF, I prefer to rotate it every day.
Spinning every day would be more relaxing in my opinion than having to collect it worrying that the price of bitcoin goes up and I get less in the amount of satoshis from free bitcoins the amount of other prizes decreases too, it may be annoying but it is a fair system and everyone should understand it and understand it .
