The fatal weakness of Bitcoin is that it needs electricity. If there is no electricity, will Bitcoin still exist?
Even if there is no electricity, Bitcoin still exists in theory, but it will lose almost all its actual functions and value.
Theoretical existence: Bitcoin's transaction ledger is a decentralized distributed ledger, and the data is stored in servers at many nodes around the world. Even if there is a power outage, the transaction information and the total amount of Bitcoin recorded in the ledger still exist. From the technical level of blockchain, the basic architecture and data of Bitcoin will not disappear.
Limited actual functions: Bitcoin's operation relies on electricity to maintain node computing and network communication. After a power outage, miners cannot perform mining operations to verify transactions and generate new blocks, transactions cannot be confirmed and recorded, and Bitcoin's transfer, payment and other functions cannot be realized. Moreover, without electricity, users cannot access and operate Bitcoin wallets through electronic devices, and its value cannot be exchanged or reflected in reality.
