In my case were i recently trading on hotbit i would say its a legit exchange, i thought i need to pass kyc just to make a withdrawal but i was wrong, and my withdrawal went smooth, they immediately process it.
From my side work fine but not legal for US citizens, that's might know for US people. Make sure you're not going to ban after sometime before you're putting money into some random exchange. But, would be good to have a look on yourself, it's not good just rely other individual guys.
