It seems to me that soslex and the other winners of the Lambo lottery preferred to get BTC instead of a Lambo. This is a more convenient way to get the prize because he doesn't have to worry about delivery and registration of an expensive car in his country. In addition, 10 BTC in his wallet could potentially make him a dollar millionaire. Of course, this will only be possible if he has enough patience to hold BTC at least up to $100k.
