Based on the calculations in the article, the cost required for a PoS attack is 4x the cost of PoW attack. While there may be some miscellaneous costs that the article ignores, it seems unlikely to change the conclusion given the magnitude of the difference in cost (4x).
AFAICT, the capital costs seems to assume the depreciation of it but doesn't necessarily consider the fact that they become practically useless after any forms of attack, completely. Attacking the hardest chain would only serve as a warning to the rest and your ASICs can all go to the scrapyard right after. Instead, take into the account the costs of the ASICs rather than the running costs due to depreciation. Silicon production industry are fairly inelastic at the moment and ASIC chips aren't the focus of chipmakers right now. Whether you can scale up the production through the years, and race against the network is another issue.It only takes a few mining pools to have enough mining power to attack the network.
For a fact, mining pools cannot sustain the attack. The miners in a mining pool has vested interest to ensure that they can continue to run pools, and their miners want to continue to mine and not have their equipment becoming useless. At the first sign of any possible attacks, the miners can easily just point their ASICs somewhere else, and not continue to mine with them. You can't do the same if your funds are trapped with an exchange.At the end of the day, I'm not going to be name-calling, whether they favour PoS or not. It isn't the purpose of my posts. I'm only here to provide my 2 cents and it is totally up to you to do your own research and come up with your own conclusion. Be objective and consider both sides of the camp, but DYOR and don't get misled.
