Btw, those 37 % are not really a stable income. You should look at the article to see how his potential APR fluctuates. After 9 days, volatility makes much more of an impact than the trading itself and the number does not really say much. And I am not saying 37% is not possible. I think that in the last year, I had more than that (but the initial investment amount was not that much)... but now there will be more market makers, of course... so who knows what the future brings.

But overall, I am pretty excited to finally have a mm war. :D
