Not surprising Tether has the highest turnover (188%) of all the top 100 crypto-currencies. The total trading of Tether is almost 2x it's total market capitalization. Interestingly enough Bitcoin (5.29%) has relatively low turnover given it's leading market capitalization position. Ether / Ethereum (4.24%) trades a bit less than Bitcoins. Both are bested by their respective peers, Bitcoin Gold (20.48%) and Ethereum Classic (21.03%). Interestingly enough EOS (35.34%) and Walton (45.38%) have high turnover relative to their larger size as coins. Both are in the top 20% as a percentile of their top 100 peers. Not surprisingly as the market cap of the coin diminishes so does the turnover of trading.
One interesting currency that has high turnover is Walton. I looked at their video (briefly) and it's has something to do with RFID chips, it should be noted that for RFID chips to work they need exposure to a power-source/sensors to active them. I don't think their business plan of rolling out a bunch of RFID chips and putting them on everything all over the world will work. The business models seems a bit suspect IMHO.
