yes. I have also seen that the market is currently very much dominated by Binance. many altcoins are gaining popularity because they are listed on the Binance exchange. Is this all because of Binance's extremely low transaction fees? so a lot of people trade on the binance exchange.
It's probably because that exchange is already popular and has covered many markets. So, any project that get listed there will have the chance to get pumped because of the high trading volume, there are probably many traders that didn't try to analyze project but buy at the time it got listed in the exchange instantly and hoping its gonna get pumped later and then make profit. Im sure the transaction fee there is the same as other exchange.
