Cryptocurrency can be a new solution in the transaction payment. That will help people to have a new type of investment with so many coins inside the cryptocurrency. But until now, the spreading of the cryptocurrency is not happening in all countries. Many of the countries have banned cryptocurrency because I think they don't understand about it. The technology of cryptocurrency can be applied in real life, but I guess that people are not ready to see new things that happen in their life. We need to wait until all countries approve cryptocurrency so that we can use cryptocurrency in daily life.
