You guys realize that at least 2-3 of those are stolen from Mybitcoin, MtGox's hack, the polish exchange hack, bitcoin7 hack, the guy that had 25,000 coins taken right from his desktop... literally you are staring at a criminal's bank account and can't do anything about it.
Bitcoin is a tea party dream.... and look how it worked out in those instances.
I love how no one replied to that one.
I still suspect one of the major holders is MtGox....anyways it doesnt matter who is holding them as much as the fact that they are hoarding it. So not only does the bitcoin economy have to produce $$$ for new coins, there is a 50% tax to give to these lazy hoarders....well the true tax is probably 90% because the other 99% is just holding onto them as well....it all adds up to a STRONG SELL on the value of the bitcoin vs USD IMO.
Its just something no one saw coming. What forces anyone to work in the bitcoin economy? Nothing....the volume will slow and eventually these types lose interest in the get rich quick scheme....they will sell part of their holdings...watch.
