Besides, I still fail to get how can bitcoins help these people: are there arms dealers accepting bitcoins?
Ukrainians can use BTC-e to convert bitcoins to dollars, and use them for things like food, water, and transportation. With the current events, some people are not able to work, or travel around the city, and need financial help to survive.
If you really want to help the Ukrainians, go over there and tell them about anarchy, for that is the true solution they are seeking.
Considering many of them are upset about failing social services and pensions, I don't think anarchy is what they are looking for.
