CH01::Mining: clarify that 99% of all bitcoins will be mined within a decade
Previous text mentioned all bitcoins would be mined by 2140, which is correct but easily confuses people who don't understand exponential decay into thinking a substantial number of bitcoins will continue to be mined for a century.
