What I meant was, it's trivial to create a view that prices all stock quote statistics in BTC rather than USD.

What I'm saying is that the actual engine of trade, the nuts and bolts of a stock exchange, would be the difficult part. I have no idea what it would take to allow customers to deposit BTC, and trade stock in BTC with BTC as the unit of account. Probably needs regulatory changes? I simply don't know enough though. It's an interesting proposition
