The marketcap.one team recently launch the first Exchange Volume Rankings exclusively for EOS tokens. In total, 10 exchanges were listed, including CoinTiger, WhaleEx and Newdex, with 39%, 27% and 23% of the total daily volume respectively.
Therefore only these 3 exchanges alone make more than 89% of the daily volumes for all EOS tokens, which is approximately $1.1 million. Apparently, though, Newdex is the exchange that holds the record for listed tokens amounting to 348; followed by WhaleEx with 119 tokens. While CoinTiger only listed two: IQ and TELOS.
