I do not share your opinion: GRIDCOIN is connected to a strong / old internet project: BOINC with a faithful user base. This user base will not abandon BOINC and some will mine GRIDCOIN whatever the price is, just because it helps pay some of the expenditures – like I do – or because it’s another fun project to be part of. So GRIDCOIN user increase might be slow at the moment as the price of CRYPTO in general is low, but I cannot see how it will dry up at all in the future.
Just do not sell, if the price of GRC is not right for you! Hodling is right thing to do at the moment!
