It's amazing that the site slows when the bitcoin from 330$ go to 450$ ?

+30$ 26 november
+25$ 05 december
+62$ 11 december
(It's little down and the 15 december (now) is the same price of the 11 december).

It's up no stop.

How buy and sell with this price. Just wait for the software take the bitcoin loose and continue to grow.
