ETC has been 51% attacked too much and technically, it cannot compete with newer projects like ICP and HBAR. As to mining, most people will move to mining tokens on Ethereum like 0xMR or will switch to mining RVN, which will be used for tokenized real estate and stocks. Current art NFTs are just a testing ground and a hook to get people interested and using the technology. You will become an NFT, just as you are now a stock certificate (SS card and Birth Certificate).
Yeah, ETC getting 51% attack was such a common thing that I have seen it multiple times within just one year back in the day. However, the difference here is that if ETH becomes POS then these miners will try to find another place to mine for, and if they pick ETC that means the hash rate will be so high that it would be near impossible to hit 51% there.
Right now, it was simpler because the hash rate was low at the time when 51% attack happened, and someone who had super powerful machines could just redirect it there and even rent plenty of places and they could just use that power to attack, with ETH gone, ETC will have too much hash rate to do that again.
