To be honest, we don't need these tons of exchange sites where in fact only few are doing fairly good in terms of liquidity and credibility. And with that, only few will survive and we can actually predict some of it now, moreover they will develop more.
I think that with the advent of DEXs, a lot of the more incompetent centralised exchanges will be wiped out as a matter of time.
Hopefully and it sucks when a CEX ask for a kyc. Wth.
