Previously, the commission rate paid by bankroll investors was calculated by converting the bankroll to
special drawing rights (XDR) using the average exchange rate of the past 360 days, then dividing the result by 55,000,000 XDR. Going forwards, the average exchange rate of the past 180 days will be used instead, allowing the commission rate and by extension the bankroll to react to changes in Bitcoin's price faster. The immediate effect is a reduction of the commission rate paid by investors from approximately 67% to 52%.
Sweet. A slight tangent, but it'd probably worth making an /invest-calculator that allows you to plug in a few variables:
* bankroll
* how much you are investing
* assume bankroll is static or not (i.e. if investors keep taking profits)
* average daily turn over
(and more??)
And gives you the average outcomes of the investment. As it's basically a calculation that investors all repeatedly need to keep making to figure out if it's worth investing or not. And it'll probably make investors more responsive, as it's a lot easier to see expected outcomes.
