So you're saying to get people involved in Bitcoin we should sell them an affordable pyramid scheme? This is exactly what we want to stay away from. Bitcoin should be promoted as a currency; not a get rich quick scam.
Forget the pyramid scheme aspect, and focus on Bitcoin and Gifting.
Lots of folks play cards and other games around the table, and bet for matchsticks or toothpicks. Matchsticks and toothpicks have value. They can be used for something useful... just like Bitcoin. Folks play the games for fun and bet for excitement, not to get rich. And this is all that people would be using the gifting for, at least at its beginning. After awhile, they would be thanking their lucky stars that they had been shown a way to give gifts to their kids and grand-kids while letting them get in on the greatest freedom-maker in the economic world.
