It has been long years has pass that Im using this exchange name of Hitbtc, Im comfortable of this exchange because of no KYC using if we are doing to register on it and I did not encounter some problems about but some people said these exchange sites has have many problems and its not safe. But we are different opinion so I must preffer always in Hitbtc. Cryptoia also It is a first exchange site that Im trading some of my coins that I have since in 2017 and I dont know if this exchange is still alive or not.
