Yeah, someone is trying really really hard to keep the price of MaxCoin down. That was a pretty blatant attempt to kick down the price yesterday. No miner in his right mind would dump such a huge amount of coins into a rally like that. Smart miners who want to get the best price for their mining investment will sell slowly over time, not in tranches of 40k-50k+ dumps. And especially not at the bottom of the market. The only reason someone would do that is to manipulate the price. If you notice though, these dumps have little effect on the market price any more. The support at 0.000125 is holding strong. Even small buys are now causing large upswings in price because the sell side of the order book is starting to look pretty thin at this price level.
