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?
I think, at the moment, the minimum cost of Bitcoin is about 5K, because the profitability of the maining becomes equal to "0".
Perhaps in the future, equipment will be invented that will provide lower cost of Bitcoin.
It should also be borne in mind that the number of Bitcoin in circulation decreases as they are lost in wallets, with lost passwords.
