If you're interested in Bitcoin, the absolute best thing you can do right now is provide viable, interesting, valuable economic exchange to the system.<p>Work for Bitcoin, offer to pay for work in bitcoin, sell your farmshare for bitcoin, etc. Bootstrapping an economy is hard, but can be rewarding as the article mentions.
The thing that will keep bitcoin alive is black market transactions. As long as there is a single officially supported currency that can be traded into bitcoin there will be a huge market for it.<p>I don't see every nation in the world banning bitcoins so that pretty much means it's guaranteed to remain viable (and more likely grow.)
