Market cap means almost nothing. The market cap is dropping because coinmarketcap lists tokens with coins. If you restrict the list to just coins, Gridcoin has only dropped about 30 places since last year.
In the past 12 months we've seen major leaps forward in the development team and a rise in community interest. If you look at CoinGecko for more useful metrics, we are only just now seeing Gridcoin starting to take off on social media and our development ranking is in the top 30 (including tokens).
The price may have dropped but the ride is just getting started.
Yea, I'm very curious when will the media start to hype this, because this coin is "sooo greeen" ;)
