Bitcoin is a decentralized automated program that means no one can control it. This marks the beginning of the end for fiat currencies. This contrasts with the fiat currencies that can be printed as desired by their central banks. This makes Bitcoin a deflationary currency, while fiat currencies are inflationary. The fact that Bitcoin is a real alternative to fiat currencies could accelerate the collapse of fiat currencies around the world that some economists had predicted, including the US dollar.
