This is an awesome thing to do. But is this based on total investments (i.e., when it shows investor profit = 0 it's over) or account-by-account? Like I'm currently down 8.26%, while the site profit as a whole just went back up to positive again.
Until all individual investors are at a net profit
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.
