Bitcoin is dropping, but my payout here is dropping even faster, now I am getting only 13 per free claim suddenly...

Shouldn't it increase when Bitcoin drops? I somehow thought it is related to USD not BTC. It should incease not decrease if that's the case.
Same here, I was getting like 24 satoshis a couple of hours ago, and all of a sudden, 13 in the last roll, maybe an anti-cheater system running amok? Ah well....
