Sorry to say but those coins are gone man.  I messaged CB support about this also and was told it wasnt even possible.  I grabbed a ton of coins at 26 sats hoping I could sweet talk them into letting me withdraw but nope, they werent having it.  I gave them an earfull about how shitty of customer service and lack of honesty it is to still allow trading of a coin they know you will never be able to withdraw.  Just another fine example of why MCT should be dealt exclusively on its own platform.  Screw CryptoBridge and every other exchange out there right now.  So excited for the future of MCT+, MDEX, IFX, XAP, and one day even MANO wants their own dex.
