What makes a coin dead? I would say when it has no active nodes, no trading volume and no development, in that order. Anyone have a different definition?
My second question, why does CMC still list these coins!?!?!?
Coin is dead if the official Github is not updated.
And why CMC still shows these coins? Because CoinMarketCap is not responsible for that, they can´t do research about 2000 coins at one time.
