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.
I am not sure about what is the exact status of bitcoin in Ukraine whether it is it legal or not. If it is not legal yet, I think they can still make a temporary exemption to bitcoin only to receive donations because they badly need it and the majority is requesting for it to be used as a medium because banks, fiats or other forms of payment methods are not yet available or complicated for now to use but if ever btc in Ukraine legal before, then we cant consider the recent event as an adoption but it is more of a publication.
Everyone will be aware of btc but there is no guarantee that they will now use it or adopt it. Those who donate are already been a btc user ever since before.
