The pumping of any token or coin will consist in the fact that some group of people will buy this cryptocurrency at the current low price and thereby increase the demand for it and its price. And where is the guarantee that some other group simply will not use this to sell this cryptocurrency at an increased price? They will get their profits, and the last investors will be at a loss. No, these games are not worth playing. It's just a gamble. As a rule, such a deliberate increase in the price of a cryptocurrency then leads to the same sharp correction and then a fall in its price.
