Not understand : difficult jump negative and payouts lower?
The thing is though everyone seems to make the same assumption that
PBM's payout Algorithm is directly related to the level of Difficulty perhaps to the exclusion of lots of other possible factors such as electricity costs,
equipment failure, building costs, heating / cooling etc etc
AND because no-one here knows exactly
how their Algorithm works it's pure speculation on our part as to what we THINK the Payouts should be !
So until PBM decide to be more open about it there's absolutely no point in getting overly excited about something which is completely out of our control
"PBM's payout Algorithm is directly related to the level of Difficulty" = GH/s !!! It is simply hash power. Just a question of Mathematics.
"equipment failure" = PBMining promised "No Downtime".
"how their Algorithm works" = The difficulty is a simple number:
$per24 = ($totalHashingPower * 25 / $difficulty) * (60 * 60 * 24 * 65535 * pow(10,6) / pow(2,48));
The mining of BTC is an inexact Science what with all the competition between the various Mining Pools for the newly generated Blocks !
Have a read of some of the Mining Pool threads and read about how many hours can go by without success ...
