Sounds to me that some people here bought at the top, and are pretty eager to blame somebody. Risto hasn't been the only one saying the price of BTC is going through the roof. The Winklvii said ~$50k...hell, even the BoA said the fair value was $1300. Don't blame others because you're a moron and can't make your own decisions. This is the speculation thread, right?
I've been making fun of him from the day he said it was going to $100k within a 12 month span. I don't let that die because from that point on I knew he makes decisions entirely on a whim.
