Because of the recent development, I think more people are thinking about a possible 51% attack. People might think that if it is possible to do a 51% attack on the XMR blockchain network, it would be possible on the Bitcoin blockchain network as well. But as we know, this is not going to be so easy. Whoever plans for it knows better than some people like me who don't have much knowledge about it.
It will be too expensive to operate a 51% attack on the Bitcoin blockchain. But is it doable? What if some companies together want to spend a huge money to test it? I assume the entire crypto market will collapse if something like this happens.
I wasn't aware of Monero's current situation and I'm fascinated that explicitely going for CPU mining over ASIC mining wasn't enough to protect the network from centralization. Funnily enough requiring ASICs makes a 51% attack more costly, given that in a situation of complete market obliteration a CPU mining attacker could reuse/resell their hardware for other purposes whereas an ASIC mining attacker would be left with a pile of worthless bricks.
