Since this is science please make no discussion about how crypto currency is bad, I think we are all in agreement it's a giant waste of electricity used only for cp and drugs. Let's discuss only ways crypto currency could be destroyed. Would introducing fake crypto currency destroy the value enough to make it worthless, or would there have to be a more brute force method of destroying the program itself or possibly targeting mining rigs with viruses? I'm not a computer expert that's why I'm asking you people.
Quantum computers
governments dicking everyone involved
51 percent attack by state
overflooding the transactions (requires a lot of capital), to render the currency unusable
but why?
Because private property is stupid I want to upgrade my computer. My 1080 is worth more than I bought it for.
