I guess it's only normal to expect the prize pot to go down over time as Bitcoin gets more expensive and more players sign up every day if it's the case of wager + free rolls taken.
Yeah, I believe when bitcoin goes up that makes people spend less
Ironically, that's the mindset which keeps bitcoin from going higher.
When people reach a certain number in dollars, they dump their coins.
Only gold is strong enough to change this and even then most people would still prefer USD over gold. I know that's crazy, but if that wasn't the truth, nobody would be holding any USD in their bank accounts now.
