Just like the other video's i've seen regarding the contest it doesn't really explain anything about Blackcoin.
I think the contest organizer was hoping he'd get a fancy weusecoins.com video...
Hello, it would be absurd enough that they should ask an explanatory video thirty seconds, and within less than a week. Clearly if I wanted a video like bitcoin is wildly wrong in the contest.
Still, thanks for replying.
