I hope Nobl Add at bittrex.
I dont use Bittrex (yet), so you guys that are there can ask them for listing it back. Google say that NOBL was there allready in the past.
I posted a coin request on bittrex a few weeks ago during the delisting phase - generally they need a few people request on there - better still is if the dev posts a request.
problem is!
it seems the dev himself abandoned his coin..
