We are tend to talk about governments accepting bitcoin and other crypto currencies. We do have corporate companies who are the main source of income to all citizens of countries. Government are the first beneficiary of these companies. The country's development is depend on outsourcing. How well it would be if corporates adapt Bitcoin, other crypto currencies and blockchain?
Companies adapt Bitcoin how? As means of investment or as salary for people? As investment then they can go and do it. But the problem is that is volatile and risky. Besides those corporate giants would rather have their own stocks so I doubt that we will see any big companies who will invest. And if ever they are gong to invest on it, I'm sure that they will go to the usual channels, big banking and investments firms and hedge fund managers. As for Blockchain Technology, that is a different thing. I will not be surpirse is they are slowly adapting it because its not costly and data is immutable. And we all know the data = money for huge companies and corporations so its possible that they are moving on that direction. As for salary, Japan's GMO has already started paying their employees with Bitcoin (partly):
