The German economy is considered the largest economy in Europe and the 4th largest economy in the world with a total GDP of 4,000 billion USD, only behind the US, China and Japan (2022 data). So it would be naive to think that the German economy needs the help of those bitcoins. We cannot know exactly why they are selling bitcoin at this time, but it is certainly not because they want to save their economy with that small amount of money

.
The return of Mt.gox or the government selling bitcoin are all good news if we ignore the short-term impact. Even for those who understand how bitcoin works, this is another great opportunity for them to buy bitcoin at a discount rather than panic selling.
Germany being the largest economy in Europe doesn't mean that they don't need the money from the sale of Bitcoin. The money might be insignificant when compared to the total GDP but selling the coins now shows that they need money. Maybe they want to use the money to finance a project or pay some financial obligations. It is also possible that they are selling to make a profit. They might have plans to buy in the future when the price drops.
This is my first bull run and I am gradually understanding the market. This is why it is important to have a Bitcoin rebuying plan. Don't depend only on signature earning to replenish your hardware wallet. Yeah DCA is the best buying strategy but lump buying is not also a bad idea. One can buy Bitcoin with a large sum if you can predict the lowest price during the bear season. I don't expect Bitcoin to get to $18,383 in the next four years, so it will not be a bad idea to buy the coin when it gets to a price like this. So as you are selling also have a plan to buy when there is a golden opportunity. German sale of their holdings and the repayment of Mt. Gox victims is also an opportunity to make a profit because by this time in the next four years (Ceteris paribus), Bitcoin price will be worth more than the current price.
