I put this under mining because you can earn bitcoin by spinning a wheel. You get 1 free spin a day plus anytime you use their card to purchase something you get a spin. I have seen 6 announced winners of a full bitcoin in the last 6 months.
There is also a metaverse game in the app that lets you win more items like crypto and spins. Sign up at https://use.foldapp.com/r/7R44P9LF and be a part of my spin squad where you get bonus spins and earnings!
