They said the free spins were removed due to problems but that makes no sense.
They never explained why they no longer credit WOF spins for holding FUN tokens.
It was removed because the bitcoin price got too high and it was too costly for them to keep those up.
No, it has nothing to do with bitcoin price.
The rewards they get through WOF spins are always adjusted to bitcoin price.
When they launced WOF spins, the base rewards were 50 satoshi, 50 reward points and 50 lottery tickets. Now they are 12 satoshi, 12 reward points and 12 lottery tickets.
