I think while there is binance, those exchanges have no chance except decentralized ones because they don't bring many differences but decentralized exchanges especially oax can gain dominance.
Binance already set the bar high, superb support, quick actions against potential threat that's why they are number 1 right now. So its up to other exchanges to catch up.
Kucoin is one of the best new exchanges and is moving up the ranks quite quickly. Just a few months ago it was around 45 and now you can see it has moved up to 38. I think it will go into the top 20 this year, lots of good coins and a reliable safe exchange to trade coins in.
If that is the case then good for them. It's a sign that they are gaining the trust of the traders but it will take some time to have trading volumes increases. As others have said, it's not a overnight process. Although I have one bad experience against them, but I think its a isolated case.
