Ukraine's Kalush Orchestra, which won the Eurovision this year, has auctioned its trophy for a $900,000 donation to a foundation that helps the Ukrainian army.

The trophy, a large crystal microphone with the song contest's logo, was put up for auction on Facebook.

The bidding ended Saturday night and was won by WhiteBIT, a Ukrainian bitcoin company.

Kitsch, glitz and geopolitics -- the Eurovision Song Contest is back in two weeks' time, with Russia excluded and conflict-ravaged Ukraine the hot favourite to take the crown.
