These two events contribute to the decline of bitcoin's price. Frantic investors have all sold their bitcoin in fear but if you know better, you know this is the right time to buy and accumulate as much bitcoin as you can.
There could not have been so many distraught investors selling their bitcoin in fear, because the greatest pressure on the cryptocurrency market could have been exerted by these two events: bitcoin sale by Germany and Mt.Gox users. The increased supply of bitcoin in the cryptocurrency market inevitably leads to a fall in value. This is a classic law of economics, the swing of supply and demand. Former users of Mt.Gox can't be called distraught investors, because their money was frozen for many years and their desire to sell bitcoin is now completely justified. Plus, not all of them will sell all of their bitcoin. Having seen the results of a long hold, some users will certainly leave some part of bitcoin for storage.
