I think you missed the best stage to sell DBG, at the end of 2017. I don't want to talk about how you are investing, but I want to advise you that you should not hold on to something too long in the crypto market. why?
Because from 2017 onwards, this is the Dumping and Pumping market type. When you are profitable, you should take profits because most of the alts are affected by the price of BTC, and whales then adjust the price of BTC.
therefore, even though it is a very promising project but it is still under the control of whales, whales can make the whole plan die within a year of dumping. good luck
