Whoa, I didn't know about that difference! But how one can roll "0" then? I think some people were reporting they got "0", and wetsuit said rolling "0" is possible? That's why I decided it's the usual rounding.
If rolling 0 is possible, the total number of outcomes is 10001. Regardless of rounding in that calculation procedure, there is no actual proof the probability of rolling a certain number is equal among all range.
So, the final rolled number is random, but not equally random (as of 1/10001 or 1/10000 probability for each outcome).
Well, not to have anything else to say over this faucet. It pays regularly and consistently.
Too bad I was too lazy to deal with bitcoin when I first discovered it years ago, there was a faucet giving out sth like 0.5 BTC for free and BTC was worth only few cents
