Support programs like paper wallets, phone apps that are secure (unlike Bitcoin at the moment), and as much point of sale as we can get increase value. Scarcity doesn't make value as much as support does however 42 coin is extremely expensive compared to Bitcoin because of scarcity.
Before everyone gets on me about how Bitcoin isn't secure on a phone. I based that on news stories I read on the internet. My opinion is if you want to loose Bitcoin just put it on a cell phone.
