Okay so I still have CDT in my MEW, I checked the coinmarketcap but CDT is now BLOX, is there anything I should be doing to convert my CDT into BLOX? Never did I sold any of it since the time I got my tokens. I still believe the project will make it on top when if there will be developments that is significant enough to earn investors trust again.
