"Investors in Bitcoin have suffered a strong correction, but
the currency continues to trade at levels more than five times higher than a year ago." Why are they worrying?
This is just a small bump in the road, and a less volatile currency, everyone has been asking for. It will go up, again when demand for the coins increase. The hoarders just went on a little spending spree at Dell for a while, making more coins availlable again, and thus pushing the price lower, it will be stable for a while, and then it's going to climb.
