Mt. Gox has started repayments in Bitcoin and Bitcoin Cash. It is not specified just exactly how much have been distributed and how much there is left however the decline of price of Bitcoin these previous days can be attributed back to this.
Additionally, Germany have also sold a huge chunk of their seized bitcoin in an operation against a piracy site last active almost over a decade ago. The exact reason why is unclear however many suspects that Germany is trying to liquidate the Bitcoins they hold to stabilize their economy. Despite a huge sell out, Germany still holds almost 30,000 bitcoins.
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.
Where did you get the information that Germany sold its bitcoins? If I'm not mistaken, they just moved a small amount of them to several exchanges, but hasn't sold them yet. The same goes for Mt Gox, are you sure they have started paying out? The market definitely picked up this news, and Bitcoin reacted with a fall, but if there is a seller on the market, then there will also be a buyer who will buy these volumes. I think the bull market is not over yet, and even if this is true and Mt Gox finally pays out, then this long story will finally be over and they will no longer have leverage over Bitcoin prices when they were able to manipulate this news every time.
