i also heard that the seized BTC was sold because court order or something, so reinvesting the money just doesn't make sense at all.
It’s not the same state that are re investing rather if true it is Berlin that is actually investing now and not re investing, the state that sold was Saxony. The order doesn’t have to be from the court because ideally it’s not right to keep the funds or property seized as reserve or anything. It’s just similar to impounded property which are later auctioned off. People actually relate this to the German government and many articles have actually debunked it a lot of time.
As for maybe the Berlin state are FOMOing by buying at the current price because of the move I would say no, the reason is they have the capacity to actually hold it for long and also are buying in large quantity. FOMo is when actually do not have the capacity to hold for long and you’re having smaller funds too. Moreover bitcoin isn’t like other cryptocurrencies that loses value easily and buying at a price like it is now will not cause much of a problem because there is high possibility of it Moving up from here
