Based on my own personal experience, Ive come to the conclusion that relying on the bitcoin faucet to reach the minimum amount of bitcoin that could be withdrawn is practically, and even technically impossible..
Except the user is lucky enough to roll 9994 and up multiple times, or the user rolls 10,000 which comes with the highest reward.
But like I said, if it's just a regular user is roll 2 Satoshis each hour, it will take several years before the user ever arrive that the minimum withdrawable amount - something I consider impossible, like I've said before.
Nothing is impossible offcourse but it will take a long while. My minimum free roll is 7 satoshis/hour and if you would not skip any roll, it would take around 178 days to reach the minimum. Nobody is on line every day, but with some luck you roll one of the higher numbers and you have daily a WOF spîn where you can also win some extra satoshis (or RP). The good old days where you would get 100 satoshi or more per free roll are over.
