I read all these threads about coins becoming officially dead. However, most of these threads are FUD. When does a coin become official dead? Is it when the developer stops developing? Is it when the coin stops trading on major exchanges?
Well at least on this forum for quite some number of people a coin is dead when is slightly worse then their favourite coin. So fro them 99% of coins are dead.
Coin dies when:
technically a coin is dead if there is no one mining it and there is no full node of it available any more.
