...but A coin which is existed in everywhere, even big exchanges but still they create fake volume on small exchanges, what this means? Why they do that? Is everything just done by exchanges or project itself, and also that makes a clear difference in prices as compared to official price of market that makes frustrated.
Like what coins/tokens?

To create hype. Some altcoins are good for day trading. Creating a fake volume will attract more day traders.
We can't also hide the fact that low market cap coins do have whales. They can create fake volume and deceived anyone. And if people fall on the trap, these whales can now execute their magic button anytime to control the whole market of that coin. Examples are BLU, SDRN, IETH, etc.
Anyhow, I don't take CMC listing as a purpose why fake volumes are being created.
