I don't disagree, but the idea that you can't use the same methodology to determine a 51% attack price for Bitcoin is just wrong. Indeed, back-of-the-napkin calculation with an order randomly picked from NiceHash[1] for Bitcoin mining and the same methodology gives: Cost (PH/HR): 0.0002625 BTC Bitcoin Network Hashrate (PH/HR): 9M 51% attack for one hour: 4.6M PH => 4.6M * 0.0002625 ~= 1200 BTC So a one-hour long 51% on the bitcoin network would cost $43,200,000 at $36K per BTC, as per a NiceHash rate I randomly selected.
