Check out the cost of running a 51% attack(50% ain't good enough), not to mention the "killing the golden goose"issue: as they spend the money, bitcoin's price would plummet. Makes no economic sense.
ah I see, you would need the ASIC miners to perform the attack, not just nodes. I am not sure why that went over my head.

You need 51% of the hash rate

I see. When it comes to BCH, is it more vulnerable to this kind of attack because of the increased block size? Does it require better hardware with the larger block size?
