Conversely aren't you also saying that MP is the worst place for investors to invest, and that they'd even be better off at PRC, paying the highest commission of all investment sites?
I don't think this is implied at all, as what investors care about is bankroll turn over (* their EV, I guess) rather than absolute commission amounts.
So far YTD investors would have made a little over 60% by investing in MP, so I think that would have outperformed most sites (primarily due to its small bankroll)
