DRGN should become another dead project soon.
You must try to take a look at the DRGN twitter account
https://coinmarketcap.com/id/currencies/dragonchain/social/This project is still actively writing the latest update related to the development progress but again the problem is there's no something useful from the DRGN development that can be useful for the investors.
DRGN could be a candidate for another scam project.
