The problem for Ukrainians is that you can't convert from hryvnia to Bitcoin directly. You should at first buy dollars which Ukrainian banks just won't sell you...
What about this then?
https://coinreport.net/btcu-biz-launched-4000-bitcoin-atms-ukraine/ The fees are a bit high, but access seems very easy. And with the Kiev Bitcoin Embassy planning to roll out their own ATMs, competition should drive the fees down.
The site has only two languages, Ukrainian and English, but their speaking heads still use Russian, lol
Not sure why that's interesting or funny. When I lived in Kiev, most people I heard still spoke Russian, and I spoke Russian with all my friends and my mom (Ukrainian with dad). It's why I instantly knew that the claims from Russian news that "Ukrainian government wants to ban Russian language" were lies. Three are probably a lot of people even in Kiev who don't speak Ukrainian very well.
Note that this doesn't make those russian-speaking Ukrainians "Russian," any more that english-speaking Americans, Canadians, Australians, Indians, South Africans, and Kenyans are "British."
