I need some good arguments for bitcoin, or at least links to the best articles you know of.  My parents, as well as many other people I try to explain the whole system to are very skeptical and refer to it as my "fake" money. I try to tell them and show that you can buy most anything with it and that it has a true use in real-life; yet they qute Warren Buffet for saying he has no money in it, among other investors.

What do you say to someone who wont accept the facts of the system? They just shoot down the "mining" process and say nothing is backing bitcoin so you can easily loose all your money, etc.

Any help would be great, or at least a reference to another thread. Thanks!
