ofc one big reason in background is that this is probably bounce from the last big down move 1163 - 382, it's not likely that we could recover this fast, despite we're talking about bitcoin
the last day of the weekend, lets see what will happen till tomorrow, although I wont sell a single Bitcoin, I am sending more cash to Bitstamp so if this really happen I will be more than happy

by posting things like this it doesn't mean that people will sell their coins, a bear market to me means "buy" a bull market to means "sell", and BTW most people have learned to hold especially after the events of this year, so I think you will see more new cash coming in instead of people freaking out and selling, the week hands already sold....
