The madness of bitcoin forks: risk, reward and ruin
https://www.linkedin.com/pulse/madness-bitcoin-forks-risk-reward-ruin-aymeric-vitte/"Conclusion: stay away from those forks, if you can't refrain then use something like my tool to transact your coins"
Solution: Transfer your coins from snapshot wallet to new wallet, before exposing wallet private key to claim your new coins. It takes you 10s to create new wallet and 5s more to complete the transfer from old to new wallet. No need for your tool to be honest. But I agree with you, always be careful with forks and with private keys generally. Never trust another person just because they seem to be nice.
I hope that "bs" does not stand for bullshit here (please clarify), as you have maybe not perceived the first article is a parody with some intentional biaised technical info, of course I am not going to give the perfect forking guide
So you agree, not agree, not clear, of course people should move their coins before claiming others (even if there are zero technical reasons to do so), now in case you have not noticed the situation can become much more malicious in case of cascading forks with some of them "forgetting" to implement a replay protection with all the other ones, then people should make sure that their coins are always "above" all the forks height, which is not easy, if not their coins could be moved without them even knowing it
The tool is for those that want to understand/master what they are doing and don't want to take the risk to use dubious wallets, or those that want to move coins not implemented in any wallet without having to sync a full node, or those that want to move coins stuck in multisig or segwit addresses, or those that just will never trust wallets (like myself)
