I am not sure that the new exchanges will be very popular. Because most of them are shit. People use mostly trusted exchanges, so newcomers need to try very hard to gain the trust of users.
traders prefer using existing exchanges which is already tested and have high security. meanwhile in new exchanges we still see high risk if suddenly be scam exchanges or at least there is no trading volume there. binance now be most popular exchange in market and i think to changed it very difficult ,moreover binance team always developt feature regularly.
