It seems MemeCoin is stuck at 0.098 difficulty for quite some time while the real coin has been fluctuating between 0.16..0.32 in reality making it ca 2-2.5x less profitable. The block count is way down too on the coinchoose.com. Right now MemeCoin:
"blocks" : 156717,
"difficulty" : 0.20253732,
which makes it ~2x less profitable or ~ equal to LTC without taking into account orphans (which are a cool 30%).
