I know Dash is *claiming* to have expanded its community but I don't believe that claim is true. For one thing, the number of tx (excluding PrivateSend bloat) is waaay down.
Even Bitcoin network's transactions have been down.
Therefore, I saw the case of DASH is a normal one, and don't panic with your information.
Total marketcap down, transaction down, price down, they are all the same in crypto during 2018, and last till early of 2019.
No reason to panic and feel negatively about DASH, so far.
