Someone or some group bought around 37 BTC worth of Colbertcoin a little over a week ago on Poloniex before they removed the coin from their exchange. The price rose to over 0.0007 BTC at the time. I'm not sure why this person or group bought so many coins, maybe they know something we don't. By the way, there are only a little over 83000 CC in existence right now.
one theory is that they are incredibly stupid.
Could be, but you never know. But I think that if someone were to spend that much money they would have to know something. Could have been a failed pump attempt too, I guess we will have to wait and see.
