The belief that the drop in price has something to do with the Mt. Gox selling is just a fantasy.
There is no evidence that the selling caused the price to fall. The price continued to rise after the selling started, and now it continues to fall even though the selling has stopped.
In addition, I also doubt that the sale of only 20,000 bitcoins for three months (the last batch of six thousand bitcoins was put up for sale on December 31, but was sold only on February 6), could crash the crypto-currency market so much. Now about 17 million bitcoins have been extracted, about 6 million of them have been lost, and the appearance on the market of such a small number of bitcoins for sale has led to such a significant fall and stagnation? It can not be. If this is so, then we can imagine how unstable the price of bitcoin will be in the future because of such cases.
