Some of us are retards, for sure. Seriously though, here's a logical argument for you: What % chance of success do you think bitcoin has? Whatever that chance is, you should hold that % of your net worth in it. We think this is going to $10m per coin in our lifetimes. That means 1% would become multiples of your entire current net worth. If you think 0% then that's fine too, but that's an overly confident position imo.
