Correction (where are you folks learning math? $400/hour, do you even have common sense?): 0.009 BTC/PH/day to buy from NiceHash (https://www.nicehash.com/algorithm/sha256 https://www.nicehash.com/algorithm/sha256) 100,000 PH/day total hashrate of BTC network (https://www.blockchain.com/charts/hash-rate https://www.blockchain.com/charts/hash-rate) That's 450 BTC/day to buy 50% of the hash rate (as if you even could, that in itself is a ridiculous notion - NiceHash says they have only 300 PH). Or 18.75 BTC/hour. Or $185,000/hour. Of course, you're not going to buy 50% of the network's currently running hash power. You'd likely need closer to 100% of the network's current hash power to gain 51%.
