I predict March-April is going to be huge for the US. TAX RETURNS pouring into the exchange(s).
I don't think any bitcoiners are getting taxes RETURNED. More likely they owe a crap load of tax, so actually they need to dump.
if you sell off bitcoins to pay tax, you'll have to pay tax on that as well. I don't think a lot of people are going to be selling much...
1)April is a lifetime from now, nobody knows where the price will be.
