Maybe a bitcoin lottery that supports good causes. It would generate some good publicity.

People choose their numbers, buy as many tickets as you like, then 30% of the money would go to support some good causes and the rest would go on the jackpot and some smaller payouts. If someone wins 1000btc that would be good publicity.  

Maybe the 30% could be distributed to African schoolchildren I dunno. I think the fundamental problem is that not enough people own BTC. And since the price rise that's only going to get worse. Big btc holders need to spend bitcoins and pay people in bitcoins especially pay people who don't own bitcoins yet.
