Main source of trading and volume is Qryptos for DRG token at the moment. After having eyes on the pattern of market how this the changes are happening in price it is some kid of suppression. It looks like some one want to shake the weak hands and profit takers to be happy with small return and to move to next. DRG token has bright future needs regular exchanges to balance the price.
You are right, now this token is strongly underestimated and only weak hands will sell it. I also believe that the project has a good future and now the best thing you can do is buy more DRG.
