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!?!?!?
What makes a coin dead for me is, no trade volume at all, 0 buyer on the exchange, listed coins only on dex exchange which is why the trade volume is low and else.
Listing coins on CMC is not that hard imo, you can listed your own coins in CMC if your coins meet all the criteria from coinmarketcap.
Sure, the lack of demand and supply, and accordingly, the volume approaches to zero. In fact, this situation turns into fear and causes to loss.
There are certain reasons for the CMC, but they are probably not being unlisted afterwards.
