Is Worldcoin fully dead?
I can't find any exchanges and any price value on coinmarketcap.
Other than still being actively mined. There is no current activity with this coin and most likely won't be until developers step up and take it over. All information about WDC can be found on worldcoin.global
Maybe if there is still mining activity this coin might be useful later even if there is no exchange. Because when everyone has been mining this coin in large quantities and there is no exchange it's the same you are like a fraud and make a lot of people disappointed, so hopefully the exchange will be available.
