As far as I know with each trading account you should verify your account correctly. Reason: Firstly, you can get the maximum withdrawal limit of the trading floor, the second you can get the best support from the trading support team. That's what I think is perfectly reasonable. You can choose Bittrex if you are afraid of having too many verifications. High stability and no need to wait too long in every transaction!
To add; if you basic verify yourself on exchanges with false information (false address, name, etc) and the exchange in question is going to subject you to the full ID verification process, you are toasted. Explain them why you put wrong' address and name data that doesn't match with your actual documents. Kiss your funds goodbye.
Some would require a selfie verification to verify that you really own that government-issued ID because it might stolen by someone or for any other reason. Our local online wallet does that. It isn't in an exchange but you can't cash out your BCH, ETH, BTC and withdraw it into PHP (our local currency) without going into those verification. In exchanges like Binance, I don't trade that is gonna be equivalent to 1 BTC so I am not gonna needing those at least for now.
