There are many exchanges that are faking volume. Some reports show that there is up to 90% wrong volume reports. With market developing i am sure there will be more strict rules and penalties.
I think this is the next step in crypto for further development.
There should be some index be issued based on volume to track real volume of top 10 or top 20 exchanges who should be then monitored by some external company.
I hope also CoinMaketCap will take this issue into consideration soon enough to get some real data on smaller exchanges as well.
I agree with your statement! Its rather be good to the community if the will not make fake volumes. Many exchanges specially the smaller one have been trying to fool traders by making a fake volume to the coin. We need a real data. This is actually one of the primary goal of cryptocurrency. People have to be acknowledge by simply telling the right information. Blockchain goals is to have transparency. I hope exchange does so.
