Moreover, I agree with the OP and in the contrary that many dump their token, perhaps trading sites isn't the one to point out. I believe as long as the project is solid and good no matter how many people dump their token, the demand will carried out.
Sure, a good product with a valuable product that is high in demand will be able to balance the equation after dumping has been done but we still need to frown at dumping done.
Because, the value also has a way of attracting users too to the product, they might have a good product that is capable of creating high demand, but something must attract the end users to it, which in this case is usually the value of the coin, and this dumping of a thing being blamed on bounty hunters is just a way of distracting people from seeing who the real dumpers are, which I typically agree with what many people has suspected in this forum, that it is the exchanges, all these exchanges too are contributing to the market fall because they buy some of these products internally and then dump it.
