I've seen quite a few articles around lately to the effect of "This is Bitcoin, it is going to be the future of money, I invested all my money in it, and you should too." As far as I know, the U.S. has some laws to the effect of "you can't buy something, tell everyone it's awesome in order to drive up the price, and then sell it". To what extent might individuals writing these articles, or the Bitcoin community as a whole, be guilty of this practice?
