Blockchain24.co have posted an interview with Joshua Frank, the TIEs CEO, about cryptocurrency manipulations. TIE is monitoring the case of fake trading volumes, and according to Frank, this is a very common practice for many exchanges. He also lists many other cases of frauds in crypto industry.
Looks like condition of out industry is not in the best shape.
Manipulation is existent to a certain extent. Even the value of Bitcoin is susceptible to manipulation given the fact that there are very rich investors. They could easily affect the price with their billions, even millions. However, we cannot say that they are really the one who dictates the whole market. Volumes are also faked in some crypto exchanges. But steps are already done to iron that out.
