AFAIK, for now only Bittrex. You only can withdraw your money ONCE you have verified your account (you need to do KYC).
Poloniex, binance, cryptopia, coinexchange, liqui doesn't need KYC unless you want to withdraw huge money.
For additional Kucoin, Okex and more exchange sites are still no applying KYC unless you are withdrawal your amount below 2 bitcoin in a day or 2 btc can be considered as maximum amount.
Bittrex and the majority of china exchange sites are applying KYC right now due to the regulations and this has already applied for all of US exchange sites too.
