I am mining xmr and aeon on MG for few months now and in my experience MG is full of bugs (or they are scamming intentionally). For example, today my aeon miner shows normal hash rate but unconfirmed balance stays at same number for more than 8hr. I got to change from PPLNS to PPS to actually start mining. Aeon got huge amount of blocks at MG pool in that 8h but my balance never get credited for that time. It is not first issue, but for me is sure last. I am going out of that bugged (or scammers pool).
