I've some concerns and queries, i observed that many altcoins even some major coins create fake volume, if a project is new and initially listed on a small exchange and create fake volume it's obvious understood that they're trying to get listed on coinmarketcap, 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.
Since bitcoin boomed last 2017 a lot of altcoins now have been created even its not that worth to invest. They fake everything just to encourage investors. That's why these days we need to be aware.
