Cryptopia is far from being a top cryptoexchange. Of course, this is better than all new little-known exchanges, but it's very far from the Bittrex level, not to mention Binance. XDNA is, what to strive for!
These exchanges are the best because the first and a lot of people use them. For example, I do not like all exchanges from the top 10, but only a few. So it's a moot point.
indeed, not all exchanges will be like all participants
if it is in the top 10, it does not mean that it is very convenient, someone will prefer the exchange lower than the top 10
