My personal opinion is that when wall street truly gets it, the bitcoin speculative bubble will make the internet bubble look tiny in comparison.
True, but they won't be happy the 1-block-per-ten-minute throttle will effectively kill any attempt to build a High Frequency Trading system. I on the other hand, am ecstatic about that fact.
Maybe I don't understand how a HFT system works, but isn't it already possible to make as many trades as you like as quickly as you like within an exchange, irrelevant of the speed of new blocks? Or is it some form of arbitrage?
