If people hold to their bitcoins, the price will go up. I see alot of people selling their bitcoins now, maybe they are being afraid of a decline. Well only the time will tell.
Yeah... there are 4 type of guys who keep selling btc. 1-miners, 2-day traders, 3-merchants like overstock, 4-hackers who try to steal coins from investors' computer. Consequently dump is inevitable.
