Binance and Hitbtc is good.Hitbtc exchange we can trade ICO also and exchange fees also less.
I don't agree with this part because hitbtc fees are quite high for some of the coins and many people are facing basic issues like coins are missing or can't see in their account. Their support team stopped to reply any of the issues.
I am trying to create account on bittrex but this exchanger close to new registration.So what is the next trusted and security exchanger?Some exchanger are so boring fro trade because of high fees delay withdraw or deposit scam etc.
Even Bittrex allow you to open new accounts no use because you need to be a fully verified member on their exchange to withdraw your coins otherwise they will not allow you to withdraw your coins. So don't deposit money into this exchange until your account is fully verified.
Other members already mentioned here about the options for you is Binance and Kucoin exchanges to try.
