I think much better to check this thread https://bitcointalk.org/index.php?topic=3028322.0;viewResults
So that you can see all the votes what people wanted from an exchange.

For me, what I want is an exchange which is secured with costumers privacy protection and add the no KYC verification which is already mentioned above. Another thing that I want is that the withdrawal limit should be unlimited without asking for KYC verified and support 150+ assets.

I don't like the KYC verification and I will never send my personal data online except for local KYC and that is why I used bitcoin is that you don't need to exchange your BTC to local fiat without verification. However, the problem these days almost all exchanges are now asking for KYC even claiming ICO requires KYC which is not fair.
