There is nothing complicated, just everything takes time. Previously, it was even more difficult when there was no unnecessary information on the Internet and all the knowledge had to be gained by our own experience.
Recently, more and more stores are beginning to accept payments in cryptocurrency, but I do not know how relevant this is. For example, for me, cryptocurrency is a tool for making money and I prefer not to spend it.
Not that they would not recognize, just many still do not understand it. A lot of people are simply not familiar with the world of cryptocurrency and therefore can not even perceive it as a kind of revolution.
Of course, crypto can be used only on the Internet, and even then not in all stores. In fact, you can purchase any product, the main thing is to find an organization that will accept payment in cryptocurrency.
