The popularity and usage of Bitcoin shows there is an emerging trend in the currency and payments market: digital peer to peer crypto-currencies. Wilson is only making a statement that this trend has materialized, and he is excited to see where it would go -- if any viable businesses spring up based on these currencies it would be a smart idea for him or other VCs to invest. Why? Well, Wilson at least is an investor in Internet products, and seeing as how these currencies are looking to establish themselves in a global market (Internet) whose GDP is in the trillions... you get the point.

Though, I do think you are biased. Obviously.
