Speech by a prominent supporter of cryptocurrency Huang Shiliang at a conference in China, which was devoted to the issues of scale, led to the increase in the number of supporters is Unlimited. Otherwise it could not be, because the conference brought together major players who are important to millions of dollars that are able to meet the requirements for generating units of any complexity. Medium and small companies, as holders of private farms should think about the fact that such scaling, although it will lead not only to a desirable increase in the cost of mined digital currency, however, the increase in Commission fees, and another increases the complexity of production. In these circumstances, companies will be very difficult to survive, they will have to merge with larger players. The Director of a famous mining company, World Mining evaluates this development as the path that will lead to a drain in all medium and small miners, to an increase in profits of the largest equipment manufacturers & largest servers, exchanges and mining of data centers. "Smaller companies will either go bankrupt or be crushed by the giants of mining", says Philip Johnson.
