Better secure those funds first.Lucky that you havent experience issues with Hitbtc knowing this exchange do have lots of complaints.

Trying to suggest;

Hitbtc -> Personal wallet which you own keys -> Create new wallet address -> Transfer the amount you would trade on new address ->
Input on DEX you prefer.

Dont make use of your main wallet even you are using a DEX same as suggested by few here.There were lots out there like Forkdelta,Bancor etc.
