When looking at coinmarket cap the top exchanges by volume are ones I've never heard of people using. is that assumption correct that they are hardly being used and the volume numbers are faked? if so, doesn't that mask real price movements from real people buying on active exchanges? It's quite frustrating and frightening that a decentralized project needs to rely on unaccountable exchanges to help set the price. The good news I suppose is a shady exchange can only operate so long before going under, right? That is unless of course they are trading against their manipulation of prices (the ultimate insider trading). The more I think about it the more it worries me. Do you think this is an actual problem, why or why not? If so what can we do about it?
