Comment Comment by TekMol $705k per hour for Bitcoin - these numbers sound very expensive.Do they take into account that during an attack the attacker will earn block rewards and transaction fees?Because if not, then they vastly overestimate the costs.This sounds like it is based on the some energy price that would be needed to do 51% of Bitcoins hashing.Doing so could very well be profitable.The reason it would be hard to do is that the attacker would have to gather a ton of hardware that way way exceeds the energy costs. parent TekMol 6 years ago

Because if not, then they vastly overestimate the costs.

Doing so could very well be profitable.
