Not controls 51% of the bitcoin, that itself wouldn't be enough. It's 51% of the mining power at any one point in time. I agree, I also wonder how much of that

Not controls 51% of the bitcoin, that itself wouldn't be enough. It's 51% of the mining power at any one point in time. I agree, I also wonder how much of that was due to lack of ability to short the price of bitcoin at the time. Nowadays you could maybe profit even if you totally destroyed the bitcoin network and made your own mining hardware worthless?
