The global economy is nearly 80 trillion USD per year. Payments using any type of cryptocurrency as a medium of payment is a tiny fraction of this total.
What are some of the reasons preventing cryptocurrency from being more successful as a medium of payment?
As far as i am concerned, a limited/lack of understanding of how cryptocurrency works is one of the factors hindering it from gaining much acceptance in addition to the fact that it will put people in control and may challenge the status quo of financial institutions. Overcoming these two factors, then it is certain that the acceptance of cryptocurrencies as a medium of payment will soar.
