all the bitcoin_forks that i have seen so far had replay protection so you don't have much to worry about. but it is best to always create a new wallet and send all your bitcoins to a new address from that new wallet, then start claiming the forked_coins. because the risk is not just the replay protection or lack thereof, the risk is also from trusting your private key(s) to a new wallet software that the for_coin team provided you with.
Very true! Ive already extracted the more "major/bigger" forks from the seed and sold them, so even if someone steals whats left of that private key, after I moved my BTCs from it, there wouldnt be much left anyways. But non the less, what you said still holds true. Thank you.
