Bitcoin Starcraft Challenge is a show match between Scarlett, the Zerg player from Canada, and NaNiwa, the Protoss player from Sweden. These are two of the best 25 players in the world and, with TLO, the only top-25 players from outside of South Korea (although they each spent substantial time training there at some point).
Of course the interesting part is that they are playing for Bitcoins, 12 of them, which has a value of roughly $10,000 USD. Thankfully there is no Terrans to drop MULEs otherwise the whole economy would collapse (I troll, they are balanced all things considered).
TotalBiscuit and other (currently TBD) announcers will commentate the event, this Saturday, at noon EST. The event will be best of 7 and streamed by TotalBiscuit on Twitch; the VoDs will be later available on his Youtube page. It should be a very interesting event.
This will probably be the most efficient way to acquire Bitcoins with your GPU for quite some time.
