it looks like they are just hanging in there ... they let these bull runs happen at the weekends to relieve some pressure when new fiat cannot get into the exchanges to send it rocketing, then save up their dumpage for a monday-tuesday dumpathon ... but it's all looking quite desperate, at some point they will run out of idiots to borrow coins from and then the market can find the monetary premium instead of bouncing along on the cost-of-production floor (which is ever-increasing and soon to be doubling anyway)
