Bitcoin is abstaining from the fact that countries are not under their control. Many even go to the road of prohibition. In fact, blockchain technology is an area where countries need to develop themselves, but unfortunately, there is not much investment yet.
The reason for low investment is the unawareness regarding this amazing currency. Even in the fully developed states, not everyone is using bitcoin technology. Where it is legal, even there people are not confident about the profits they could gain from investing into it. All these factors and many other contribute to less profit that countries are making from this amazing creation. People should take keen interest in it.
