I like no kyc exchanges, please do not advice me to use any kyc exchange. I prefer exchanges that do not demand for kyc or the ones that makes kyc not mandatory?
You can use Binance and OKEx exchange, they are reputable exchange so far. Also, you don't need to give your personal identity as long as your withdraw amount is less then 100 btc per day.
As for the exchange can freeze the user's asset you can read their term service before create an account. Each exchanges will have different rule or different authority to do that.
