Another free money for those who are holding large amount of bitcoin. Whatever what fork they do, I don't think that there's something that can replace bitcoin. People are just waiting for another round of airdrop.
You are right. But since it offers a free coin, I see no reason why no one will embrace it. All this forks will just be affecting the immutability of bitcoin if they keep happening. Like you said though, everyone obviously is set to dump their coins immediately on arrival, so it is whoever dumps first that will take the lion share.
