Hey, I found another article relating to this, in this one it assumed that the attacker just buys the hashpower from Nice hashable, which would reduce overhead costs massively. With Bitcoin Gold and Verge having some trouble with attackers lately I would love to know if these figures are accurate.

Looks accurate for me. NiceHash has 84.09 MSol/s that could be rented for Equihash (though it would cost quite a bit of money), and BTG has a total network hashrate right now of just over 23 Msol/s, so someone could rent from Nicehash and become 75% of the BTG network.

Verge uses Scrypt, and has 2.38 TH/s on the Verge network. NiceHash has 20 TH/s that is rentable, so with enough money (renting 20 TH/s for 1 day costs ~15BTC), someone could become 90% of the Verge network.

Thanks for the insight, seems very interesting to me. Do you think this might have an effect on POW coins with low hashrate to switch to something like proof of stake or other alternatives to ensure security in their network?
