The article that you've post here is outdated, certain information or changes are done. For example the mining, a lot of miners stop mining Bitcoin and I think that is the reason for the quick dump though it did not really last. Bitcoin is now far from it's beginning, it is now in the mid-game. A lot of things are happening that can affect the price of Bitcoin and if the guess about miners are true, I guess we need to brace about it.
It is just a normal reaction for all the Bitcoin investors to either be deppressed after heavy loss on its investment in the crypto market. money is not easy to come by. But we understand the risk factors involved upon investment. What seems to be alarming in the market are the massive sell off and very little are the buyers simple because of the Fear factor now experiences by the consumets investors. Low confidence level is now felt or experiences but i am optimistic that Bitcoin will rebound to a more comfortable level of market trading soon... Hold on it will come soon as we expected.
