Calm down. No one can dump coins on the market just out of free will. If a sale of coins is needed to fill up certain financial gaps (whatever they may be), they first have to gain approval in order to actually proceed with the sales. On top of that, we don't actually know if there have been any coins sold. It's just that coins have moved, but that doesn't mean anything. It could also mean that authorities are securing their backups by properly distributing everything. Or they are just preparing different blocks to sell them through private auctions or whatever -- there is no point in speculating about this until they come up with a statement confirming or debunking all the dump stories.
