What is the price at which a coin is considered dead or when an exchange decides to delist the coin?
Like bitcoin was 20k in jan so if it reaches less than 1k we can consider it dead?
The price of coin that is falling does not determine it is going to die. The factor that you can consider that it's going to die is when most of the supplies of the coin got hacked and the aftermath is price crash. So you could easily tell even before the price falls when this kind of things happens.
