Bitcoin is growing exponentially. At this rate, it seems the usage should double in the next 5 to 10 years.
Well this is a very good news regarding that circle would able to adopt bitcoin on next 5 to 10 years but i think they are late enough to engage. If they decide to adopt bitcoin then its the best time to do it now since bitcoins is only at its earlier years or maybe they are just waiting for the exact time when bitcoin reaches a particular time or year.
