I will expect also 300$ in this month or february... could be a reasonable price...
but for the period... in the long time we see again 400-500$ ...
I do not think that cryptsy "hack" which may be fake, has something to do with the price fall
The main reason is the devoleper and the new York time article which spread a lot of pessimistic so a lot of people are selling.
it's a strange period... see the oil! the price is a joke! A lot of nation cut their expense.
See china! The stock exchange lost more than 25 % in one month... I think that there are also other explanation, but I remember mtgox also local national news talk about it!
And another theory.. if people is scared to take btc inside an exchange (like kraken - btc-e) and decide to withdraw scared by criptsy collapse and price dump?
We can't now... but this a "strange period" (my 2 cents or my two mBtc )
