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).
I would be extremely cautious trying to redeem these, I would do it like this myself. Move all funds to a secure wallet. Never accept funds to that previous wallet. Redeem via private key by the most valuable coins first (bch, etc) go down the list and remember to dump these coins for real Bitcoin with your real wallet address.
If you randomly pick and choose which one to redeem you're more likely to come across one that uses a script with the private key and tries to redeem all the other forks before you do.
