MPH had very bad luck lattly while F2pool had extremely great luck:

And now we see that MPH posted this:

- Several coin network were rolled back by 51% attack these days. Pool increased minimum confirmation num for some coins. You may need to wait longer to withdraw mined coins than before.
the block confirmation now is " 120 confirms.".
What do you think, how F2pool got so lucky with ~130Ghs?
I asked about this on zcoin thread but no 1 seemed to care :-(.

an attacker with majority power can:
Reverse transactions that he sends while he’s in control. This has the potential to double-spend transactions that previously had already been seen in the block chain.
(The attacker could spend a coin, then create a new fork in which those coins were never spent, allowing the attacker to spend the coins again).
Prevent some or all transactions from gaining any confirmations
Prevent some or all other miners from mining any valid blocks

F2Pool have encountered a bug of Zcoin, and created an side chain unexpectedly.
We have roll back mined blocks on our side chain. Daily payment is postponed until recalucation is done.
You may notice a decrease in balance because difficulty of side chain is lower than main chain. Sorry for the inconvenience.
