Price is wavering back and forth at the moment just on the edge of the base reward being one way or another. I worked out if I buy wheel spins at the lower cost and realize the higher base reward after BTC price drops its a daily 2% yield on just that simple back and forth. Definitely seems worth doing, though its only a small amount it happens so regularly I might as well use what I got as the opportunity presents itself.
BTC wont waver forever but its often doing this kind of behaviour, I'd still class it as underlying positive though it pulls back from its gains.
That can work but also remember that you only have a 1/3 chance to win satoshis. Offcourse you can lucky aven get a higher amount than the base prize but I also looked at it before and I don’t see any clear value in doing tricks like that.
