Interesting...  We earn a prize between 47-400 (rarely) satoshis, but when we lose, we always lose 500 satoshis. You win probably 5 times, but if you lose only once, all progress is over. It can be an infinite looping of earnings and losses making impossible to reach minimum withdraw 25.000 satoshis.

Would be good if you pay players via FaucetHub.io with a lower threshold and add a countdown time each round, but decreasing the losses, increasing the chance of profit.
