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.
