It is true that Bitcoin has a bright future as a digital currency because most of the business and services are going online now so a digital money is a must and it is offering a faster and cheaper(not so cheap right now) rate of transaction anywhere in the world.
I don't think that a single company will use Bitcoin as their local currency though, let Bitcoin be a digital money then that's it don't wish it to be a local money. Bitcoin was created for the better good and convenient of the people who uses the internet so let's just wish all the best for it.
