Here is about the time that I say to buy but....
At this point, i've seen a good coin go two ways, if its time to go up, it will go up from here and not any lower. If its going to go down, for some odd reason, it will sink much lower so...
With that being said, I am buying right now but it might be a time to wait a few more days and see what the market says due to bitcoins huge jump (woot woot!).
