Maybe I'm naive, but I think investing is a noble thing to do.
Damn straight. Real world economies would have a little less trouble these days if the ultra-wealthy of the world actually moved that money around rather than sit on it.
Investing does actually have economic benefits..assuming we're talking long term investments versus day trading the shit out of a stock. Just like here in the community and under our own exchanges, investing allows the community to support various business ventures, which in turn helps to expand and promote not only the business, but bitcoin as well.
