Are you sure?
Say for example, if someone invested 1 bitcoin, lost 8% (=0.08 btc), divested all his balance except 0.00001 btc, it would take forever for that remaining 0.00001 btc to grow to 0.08001.
So if ranlo (or any one single bankroll investor) divest most of his investment, his investment profit will stay negative forever.
hehe, or if a mega-whale investor diluted everyone I'd be with out commissions for a while too

Ok, how about until the investor profit are breaking new highs, i'll keep donate all my commissions to them =)
