I get a % share in the BR and based on this I receive my Interest..
How do I make less the more I invest?
Suppose that the bankroll before you invest is 5000 BTC, and that over the course of your investment players lose 50 BTC.
If you invest 0.01 BTC then you have 0.01 out of 5000.01 and earn 0.0001 BTC which is a 1% return.
If you invest 1 BTC then you have 1 out of 5001 and earn 0.009998 BTC which is a 0.9998% return.
If you invest 100 BTC then you have 100 out of 5100 and earn 0.98039216 BTC which is a 0.98039216% return.
If you invest 5000 BTC then you have 5000 out of 10000 and earn 25 BTC which is a 0.5% return.
The more you invest, the smaller your percentage return (assuming your investment doesn't entice new whales to play and lose).
I feel dumb that I never realized it worked like this.
