'if it's true might see new dump(s) soon
Do we know how much they have dumped yet, so we have an inkling of what's to come?
Sure, 4000 coins is not much more than what's mined in a day, so it's nothing we can't handle, but it will drive down the price for a while.
Although they are selling some BTC, they're mainly not dumping, but paying people in BTC. However many of the people they're paying might (probably are) selling some or all of the BTC.
Full details here:
https://blog.ethereum.org/2014/08/08/announcement-on-planned-exodus-withdrawal/According to that, the absolute maximum they will withdraw from their wallet is 5000 BTC (but probably only 4150 BTC). And a chunk of the coin they withdraw will continue to be held as BTC anyway. Some will be sold. And the biggest chunk will be paid to third parties as BTC (who of course may hodl or sell).
Doesn't sound like enough to really move the market, IMHO.
