The beauty of Bitcoin, and blockchains in general, is their decentralized nature. Thousands of full nodes across the world store the immutable Bitcoin blockchain on their own local disk space. The current size of Bitcoin’s blockchain is about 155 GB allowing it to easily fit on the harddrive of any computer made in the last 4 years.

In order to truly destroy Bitcoin an attacker would have to destroy every copy of the Bitcoin blockchain. With tens of thousands of copies of the Bitcoin blockchain stored across the globe many believe the only way to do this is global nuclear war. While the Electromagnetic Pulse (EMP) and subsequent fireball would wipe many hard drives clean there are undoubtedly a number of copies of the blockchain stored in Faraday Cages and safes that would be protected from the EMP.

Essentially, in this scenario Bitcoin would be killed because, well, humanity has been killed. Any humans left would not have the electricity or internet to run Bitcoin and honestly would have much bigger problems than needing digital money.
