What do you think about WhiteBit exchange? 

- According to what I searched about this exchange platform it has a good and high
  volume in the market according to the latest updates on cmc https://coinmarketcap.com/exchanges/whitebit/
  Though I never try to use this one yet.

is it  secure?

- If I am going to base it on CMC my answer is I think yes.
 
But I read in some thread section in local, that there are some whitebit user complaining
about the rules of No kyc, No withdraw but before they announce it the users deposited
to their platform amounting 1000$ then 3 days after they've implement that rules, were that user
didn't apply kyc yet to whitebit.
