So obviously, they've missed out, but then again, it's not too late as every countries is talking about investing into Bitcoin and making it their national reserves. And with the incoming President of the US talking about it, definitely it has a ripple effects on most countries around the world.
You can follow it here if they made the purchase or not:
https://intel.arkm.com/explorer/entity/germany The news was a bit exaggerated because Germany had not previously purchased bitcoin and they did not have any bitcoin reserves because the bitcoins they sold were obtained through confiscation. The author does not understand the meaning of loss and maybe he does not have a view on what is being done so the writing that is published is more about the meaning in a more general sense. If it is said that they want to reinvest then they should have done that before but they did not and I think it is just a matter of bookkeeping from the confiscated bitcoins they did before.
But if they start thinking about investing it should be a positive step because they are starting to see something better in bitcoin. So considering starting will be one of the right steps because Bitcoin always provides maturity in personal, group and institutional investments.
