From 2099 till 2140 (when the last satoshis will be mined) there will only be one bitcoin mined. By the end of the century, supply is virtually fixed and limited to the maximum of 21 million. For the following forty years, miners will be mining only one bitcoin...
One of the cool things about bitcoin is that it has a mechanism to prevent crazy production of bitcoins. It will be great to see how things pan out once the 21 million bitcoin is reached. Thanks
