@Haliburton: I can get you some Fork dust to enforce replay protection, and you'd make me really happy if I can get some unsplit Fork dust in return.
How do I do that? Please let me know via PM. I will try to cooperate with you in every way possible.[/quote]Getting some small unsplit Fork dust is easiest if you have one very low amount (say 0.001) so you can only send that amount on the BCH/BSV/BCH-A chain and don't have to split the change after that. Assuming you don't have that, it's easier to forget about my request.
Replay protection is easy: all you need is a very small amount of BCH/BSV/BCH-A Fork dust (that only exists on that respectiv chain) on one of your current addresses. Wait for it to confirm, and move all your funds on each chain including the Fork dust.
But first, move your Bitcoins to safety
Question: if you created new wallets on Electrum, did you do that on an online system, or air-gapped offline? It would be an unnecessary risk to replace your long-term cold storage retirement fund by a hot Electrum wallet.
