The Bitcoin agreement also halves the amount of new coins to be mined every four years, while limiting the eventual total to 21 million bitcoins. This puts the number of bitcoins in circulation very close to a curve, and will reach 21 million by 2140. Because bitcoin is mined at a rate that decreases over time, Bitcoin is a deflationary currency in the long run. Moreover, you can't "inflate" bitcoin by "printing" new bitcoins.
