I don't think everybody will accept bitcoin in the next five years. The real problem is the government, regulators, and the bank. Instead of embracing blockchain technology, they have to protect their traditional system for "small" profit.
I think in the five years of Crypto Currency it can be more embraced by others such as institutions or universities and it can be more efficient because somehow in our generation it can be more useful and helpful for us. I believe it could be more useful for me.
