#Биткоин has the following stable factors:
decentralization. For Bitcoin to cease to exist, it would be necessary to destroy all the nodes in the network, which is practically impossible;
no permissions. Bitcoin does not require third-party approval to send transactions, which is especially important during the apocalypse;
security. The SHA-256 hashing algorithm makes digital gold virtually invulnerable to hacking;
offline transactions. Bitcoin is data that can be transmitted in a variety of ways, including radio communication.
