Umm.. well.. seem like it fall back to 280 again.. no worry. Coinbase gonna pull Bitcoin back to 300 again.
You will know when they decide to go all in.
I think right now they are positioning themselves for the Next United State Marshal auction of the Silkroad BTC sooooo.... $300 by tomorrow? Only if speculators push it there, simple math and shooting fish in the barrel for some.
