Math does make sense if the same volume is played as price rises however you are also correct that would hit a ceiling at which point it did not as players would simply play less coin. So one may see a increase for a short time then flattening out or adjust as players adjusted habit for value. The same may be said of a price drop I suppose.

So yes good catch sir but the valuation was based on todays value any ways $200-$300 BTC. 

At the current time the math makes sense minus potential increase due to BTC increasing but rather I should have stated popularity (more sign ups/players) WILL increase revenue.
