> They don’t provide an analysis of the true cost of launching a 51% attack. Andreas Antonopoulos has done this many times already. [VIDEO] (one of my favorites and only a couple minutes long) [LINK] [LINK] [LINK]

It should be noted that the bitcoin network does not need to consume more energy to scale up: - Using more energy does not translate to more transactions committed to the ledger. Second and third layer solutions can handle the world's transactional need with minimal energy usage, still using the security provided by the bitcoin network. - The security of the bitcoin network is not dependent on the amount of users, and mostly driven by financial incentives. However, the more energy it uses, the more secure it is against attacks. As it is, the bitcoin network does not need to use more energy, and here's [0] a succinct explanation as to why. [0]: [VIDEO]

it’s basically impossible to sustainably 51% Bitcoin or ETH at this point. You could 51% for an hour (maybe, if you can get that hash rate from nicehash for that long, but I doubt you actually can), but what happens at the end of that hour? Would everyone simply throw their hands up, allow your double spend, and keep mining your chain? Likely not. Andreas Antonopoulos has a good take on this for Bitcoin: [VIDEO]
