Exactly it doesn't help crypto sphere at all that;s why they need to be removed
Those guys don't exactly publish their trade volume, so it's hard to tell who the big dogs are.
Oh regarding trading volume we have someone working on putting dots and marking their address as well as help of one useful tool that's allowing you to look at records i mean not exactly sure how they obtain that data it's high possibility they dust wallets of various services via deposit and than just follow it than mark on their website but we verified as third party for our own porpoise is data really what that "site" is showing true and yeah the data they display for example ownership of bitcoin address is 100% true,In one of the statements Changelly's holding company stated they have daily trading volume of
50 Billion (probably true if we merge all their projects)
their own words published in Russian to flex on other companies in semi closed russian forum,that trading volume probably is accounted in some weird way as explained by one crypto friend of mine which he will provide his full statement soon
