Not sure that I would call it adoption but it surely gave Bitcoin A LOT of publicity in terms of being a currency/asset that requires zero permission. It's just unfortunate that a lot of people had to realize it only when in times like this — like they had to literally see it with their own eyes instead of just realizing it through studying it.
It should confidently be called an adoption. A government cannot officially release an address for donation for what they did not adopt. The adoption must not necessarily follow due process. Perilous times necessitates innovation. So, no matter the process of adoption, it is an adoption. A government that has received help from cryptocurrency can never, I repeat, can never have the guts to punish her citizens for involving in crypto.
