There are already 2 ASIC resistant forks of Bitcoin, namely Bitcoin Gold aka BTG and Bitcoin Diamond aka BCD. So, instead of changing Bitcoin to Asic Resistant, it is better to change your BTC holding to BTG & BCD.
bitcoin gold the fork that was 51% attacked quite successfully? yeah how about not.
Yes yes I know that not one entity can control it but if the 3 largest pools decide to act against it,
they can.
except these are just pools, and the pools do not control the miners and where those miners point their hashing power to. if the pools did decide to band together (which i personally think is extremely unlikely) and launch a coordinated attack on the network, the miners can choose to stop pointing their miners to the pool. The way you try to explain to this is only a half truth, in reality it's a lot more decentralized than you're trying to make it seem.
