Article misses the point (perhaps due to their capital investments) that the resurgence in active trading is almost entirely just gambling, but exempted from casino regulation. Also, saying "no more" to refer to a blip fad is a ridiculous healdit.
I agree that there is a lot of gambling and excessive risk taking going on. And I myself stick to a 3 ETF portfolio because I like the simplicity. But to call it almost entirely just gambling I think is missing the point. There is some interesting and good stuff happening now in the intersection of social media and low cost trading, and it makes sense I think for VCs to be investing in that space.
