Andreas Antonopoulos - 51% Bitcoin Attack

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: link to this video

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.

…ket cap—that's a lot of incentive to stop bitcoin from being destroyed. Even China knows it's better for them to have a non-sovereign store of value that's not the dollar. It would be pretty easy for the rest of bitcoin to see that the block is not legitimate and ignore it. Don't believe me? Bitcoin expert Andreas Antonopoulos said the same thing: link to this video . It would take a lot of coercing to convince these miners to destroy their lucrative businesses for what would essentially be a one-time stunt that only effected a block these particular miners cared about. I suspect many of them would cho…

It will never be cheap enough to 51% attack either and even if it was attacked, it wouldn't matter. link to this video link
