So what's everyone going to do?
Can see this going one of 2 ways:
(1) The 174K BTC are auctioned off at a discount and combined with the flood of injecting 1% into the market causes BTC to drop
or
(2) The 174K BTC are auctioned off at higher than $600 per coin - it's not easy to obtain chunks of BTC of that size (i.e. VC's or companies with long-term plans for BTC) and BTC continues to rise
Or everyone sits tight and waits while nothing happens.
They're auctioning blocs of 3000 BTC.
According to BitcoinAverage, over 78,000 coins were exchanged in the last 24h so it probably isn't all that hard to get "chunks of BTC of that size".
You want 30,000BTC by June 27?
Just buy 2000 a day between now and the auction, shouldn't affect the market all that much.
