to win 1 btc?

@phrequenc No why would they put up 1BTC as a rat race for the general public...the motive behind why this "sweepstakes" exists is unknown is what I mean. Why people would want it is easy to understand hahah ;)

Just another form of marketing. I am sure no one will solve this one.

It just sounds like a total scam to me.

Marketing. OP sells cards and posters.
