That's right. While bitcoin is relatively young, with its help converts one currency into another.as well as bitcoin is a means of accumulation of assets and many other functions that are not inherent in Fiat money..And undoubtedly bitcoin, whatever you call it, has a value that the crypto community determines. The next step on the way Bitcoin evolves is its use. I see no reason to consider Bitcoin financial pyramid.As for the practical use of the dollar, this argument is as inappropriate as the practical use of any currency.I suggest you read the Internet with information about the causes of the appearance of money and their use since the time when people began to evolve.After reading this information, I am sure that the questions you will have much less than now.Now in my head on the basis of the above I came up with a quote -,, no matter what the name of the money you can't eat them instead of breakfast.
