I think the practicality of the attack will still depend more on the price of bitcoin at that point in time than it will on the sudden availability of all the least efficient mining hardware. At some point obsolete ASIC rigs should be coming on the market for cheap (but right now the reward isn't anywhere near 'full' in terms of the amount of electricity apparently being used to chase it). (FWIW, I expect a crisis of confidence long before 2025. Let's see how many miners are left after that happens.) |
