I believe that the crypto currency is not a bubble, but a planned development of digital technologies that are trying to simplify every sphere of society's life. the volatility of the crypto-currency is not related to the result of speculation, but to an assessment of their base value. and the fact that the developers of many promising crypto-currencies are developing and promoting their platform, is not talking about their desire to first increase the rate, and then dramatically crash it, but that the technology of blocking is being improved, and the benefits of this or another crypto currency are increasing it in the capitalization rating, because investors are interested in what benefits society.
