Yeah, it's a bit of a chicken and egg problem: without its use in trade, it has no real value as an asset. without its value as an asset, it has no use in trade.

Fortunately (it seems to me), speculation on eventual widespread use in trade has temporarily bootstrapped its value as an asset. Now, we just need widespread recognition of its value as an asset in order to ignite widespread desire to trade for it (or at least for some derivative of it).
