hi, i dont think so it is the exchange of bitclave, as you know if you will just click deposit on your account, notification from hitbtc will pop up saying,
Please note that CAT is an IOU for future issued token. Until the blockchain is released withdrawals and deposits are unavailable. Please accept our apologies for the inconvenience.
so just for the benefit of everyone, it is not yet available to trade on hitbtc.
you are right its only IOU in hitbtc,, but how about bibox, did you know about it?
