Far as i know, all the news about regulations and all that shit were false. They were a HUGE fud in order to make people sell (and in fact, that is what happened a few days ago) So no, for me, there isn't any regulation or just bad news.
The news of a potential US government shutdown seem to be in sync with this 8% bitcoin rise. Coincidence or not? It was going up anyway and this seems to have triggered a pretty nice green candle.
