I am not sure people understand how pumps works. If you have noticed, the coin for sale on the sell side, has not changed in response to the dropping price - ideally, you would see Asks, decrease in value and get closer to the trading price. But, in Mooncoin, people have not changed their orders - why?
Blind optimism? I dont think so - they have a 100 other coins to speculate on with much thinner sell walls to beat.
Fake Sell Walls to push down price? Yes - there are 7.3 Billion Mooncoins for sale on Cryptsy (30% of all mooncoins in existence). My guess is that someone with a large horde of Bitcoins is pushing the price down (probably trading with himself too to fake some volume) and then all the sell walls will be removed for a massive, violent pump.
Just a theory.
I'm buying as price drops since Mooncoin will reach a block-halving before anyone else will (unless I am mistaken) - ~960 blocks a day = halving in 2 months. Halving makes alt coins fun.
