Why Poloniex is included in your list this exchange was a scam since 2017 and it must be removed from your list.

And take note of CoinEx exchange they are good site where you can trade without KYC but if you forgot your password and you are attempting to recover your account CoinEx will ask for KYC verification. I have issue recently with them all my mine coins are automatically transferred to their exchange(From ViaBTC to CoinEx) the problem is I'm planning to withdraw my funds from them but I can't able to login I don't know why but I'm sure my password is correct that is why I ended up using forgot password and it requires to pass KYC verification with your selfie including your fan sign that you are changing your password after giving them it changed and can able to login again.

So if you are using Coinex make sure that you are ready if this will happen to you the same as mine because KYC is required when resetting the password.
