To be more precise, if it were not for the loss of the speculators. Yeah the casino makes a profit on the roulette too, after all, exchanges and casino's provide a value added service, but not the gamblers.

Dont get me wrong, I dont think you can blame them, or enablers of services that empower them. You cant expect them to go against human nature and seek a profit if you believe in capitalism, so the problem Im afraid is more fundamental: without any possibility of regulating or taxing, I dont see how bitcoin is going to get out of this viscous circle of volatility, but it will be interesting to watch.

I do fear for bitcoin to have a future as a trade facilitating currency, rather than as casino chips,  someone is going to have to come up with a bright idea for bitcoin 2.0.
