I understand and you might be right.
But consider that coinmarketcap Volume Ranking has such an important Value as it an exchange is trustworthy. People will look for trustworthy exchanges and leave out the rest.
All Good So far - but this also motivates (all) exchanges to manipulate this (not just vitex) to signal more trustworthiness.
Not using ViteX for wash trading is like blaming Lance Armstrong for his EPO usage - sure you are right - but are the alternatives clean?
To date - I benefited from ViteX and their dividend distribution - furthermore the concept is strong. Only would like to see more active usage of the discussion board.
Anyway, best of luck to you!
