I dont think we can get the highest reward 10000 satoshi
because the chances is impossible 100 (101%), 10000 (< 0.1%)
Why reward 100 sat with 101% chances? And 10000 sat is 0.1% its smell fishy
They said it's a faucetbox script bug.
So there is a very very little chance to earn the 10000 satoshis, maybe you can be very lucky to get it.
