If I am not wrong this token was listed in May 2019? And it recently made new high. After listing also unlike other tokens, price if COS is going up.
It was listed at first on Bilaxy in March. But the trading volume there is negligible. The most important listings were on Binance. Not long after the listing on Binance DEX in June it reached the current ATH. And after the listing on Binance earlier this month, its trading volume spiked to more than 60 million USD.
Listing at Binance exchange itself is big factor for Contentos, it's one of the top exchange and ( I hope I am not saying anything wrong) only good project gets listing at Binance.
