If I am correct Bittrex was charging 5 BTC to list a coin. But It was last year and since they may have changed the rate with the bitcoin value
Kucoin is based on vote and each vote costs 0.5 KCS and each user can vote up to 50 times per project
Yobit listing is based on auction More BTC in Yobicode - more chance for listing
Poloniex doesn't charge a fee, it's based on multiple criteria
HitBTC same as Poloniex
Crypto-Bridge charges 2 BTC
Bitlish doesn't list any coin
The exchange that received the highest fees is Binance with $1M, other decentralized exchanges receive less amount.
Binance isn't decentralized
Edit: sorry, Bittrex says it doesn't charge a fee according to
thisBittrex does not currently charge a fee for listing a token on our Exchange. We believe in promoting the blockchain industry, and we have spent, and will continue to invest, significant resources to review tokens for listing on our Exchange
