I sitting in gridcoin almost a year in boinc few years and when you compare gridcoin from october to now you can see over twice lower magnitude but not twice higher price for gridcoin. I know gridcoin isnt about earning money but you can say whatever you want but gridcoin gaining most users during jump on price. Check grcpool stats: https://www.grcpool.com/report/poolChart from day 313 to 356 pool gained over 4 000 users and growth was much faster than ever before and now. why? because that was the time when gridoin price went from 0.04 to 0.17$. As you said many coins are useless they are about making money but this is crucial point for most people. I started when I first calculated gridcoin can pay around 70% electricity bill for my pc during crushing boinc and I said yea its worth it. Right now gridcoin can pay around 30% of electricity bill for my pc. For me its big minus because my previous boinc account was really good and I left my old account for going to gridcoin which right now isnt worth it for me and for sure for many others too. If gridcoin will still falling in rank on coinmarketcap sooner or later markets abandon gridcoin because there is much more bigger coins to deal with than gridcoin.
