I actually feel like the playing field is more uneven between individuals and firms in the regulated stock market vs the btc exchanges.
I also think the bitcoin exchanges are backroom dealing and insider trading, but I feel like they are less sophisticated vs the "legal" theft that is taking place on wall street.
I mean bitcoin exchanges are certainly the wild west, but I honestly don't care if people want to run pump and dumps on unsophisticated investors. That is something you can pretty easily defend against by doing your own research. There are far more nefarious things going on on both bitcoin exchanges and the real stock market.
