Now OP i have a task for you. Tell us an easy way to claim all that shit. I have never focused on forks before apart from the most popular ones (BCH, BSV, BTG), but if I could sell some of them and get some more BTC then why not. My only concern with claiming these is that some of the software might compromise the security of my BTC, although I have old addresses that technically could be used to claim some of these forks and make some free money.
Yeap, it isn't farfetched to think some of the forks could have been releasing software that could probably be used to steal funds. But seriously, the other forks besides the three you've mentioned isn't even worth selling(better yet, the effort of splitting the coins) unless you're a bitcoin whale(which is most likely not the case for like 95% of us all here on Bitcointalk).
