I mined BTC around the first halving, have some left, that I'll HODL, I never bothered to look into any other coins, as it was a free-time project and not a lifestyle. This probably means that I have some bcash etc. if those forks happened when I had my BTC on wallets that I still have the keys for. I have thought about if I should investigate that and sell it for BTC, but given the low value of those forkcoins, it hasn't been of any priority, I more or less consider it lost. I don't know if there are KYC-free ways to exchange them now, but when the EU's cryptocurrency regulation goes into effect, there won't be. Possibly peer-to-peer, but that would require finding someone who wants them, and, as I already said, not much value, so I probably won't bother.
