There is a pretty good chance that this person's post was single-handedly responsible for the 15% increase that just happened (and that began at roughly the same time as this person's post here). A single unsubstantiated comment by some anonymous person on a forum.
Didn't the severe uptrend start hours ago?
Yeah, but then it went down again, then came up again, then down, then up and hovered around $220 for some time, and then at about the time of this post it went up again by about 15%
no, it's how you juice bitcoinbuilder.com
buy - put out a rumor - sell for 20/25% more.
It would be a lucrative scam, BB has some good volume.
