What can crypto EMP destroy?

I understand that the term "crypto EMP" isn't a universally recognized term in the cryptocurrency or finance industry, but I'll assume you're referring to a hypothetical scenario where an electromagnetic pulse (EMP) is used to disrupt or destroy cryptocurrency-related infrastructure or assets. Given that assumption, I'd pose the question like this: "What specific aspects of the cryptocurrency ecosystem could potentially be destroyed or disrupted by a crypto-targeted EMP attack? Could it affect blockchain networks themselves, or would the damage be more focused on hardware like mining rigs, exchanges, or wallets? And to what extent would such an attack threaten the security and stability of digital currencies and the broader financial system?
