I got another question about CFD. I read your site, but it doesn't say what the vertical lines represent on the CFD graph. Could you kindly explain this to me. Why does it take so long to hit 100%, and what math would you do to calculate what 100% is?
You can't hit 100% becuase there is always a chance that you won't find such hash at all (with a specific transaction pack and other variables that are changing constantly, so you don't need to fear this :).
So you can calculate for 99.999999...%, but not 100%
