So you just double your money?

Only if tokens on each chain have the same value, which is unlikely. For example if you had any btc before 2014 you have the same number of sats in bch and bsv, but both of those trade way below the btc price

You are assuming there will be replay protection which will only occur if we get a user rejected soft fork, which core seems unwilling to do.

In that instance, you'll have to remove your coins to a new wallet from the bip110 fork fist, since, unless I'm mistaken, that does have replay protection? Then the core side of tue fork will be unaffected. Do it the other way around and your bip110 coins will be gone.

You can mix a post-fork utxo into your BTC move transaction and the fork coins will not replay the tx, bc the utxo only exists on the BTC side.

That'll prevent it messing with the UTXOs? I suppose it makes sense. Long time since having to worry about this.

Yeah, if the transaction is replayed on the fork chain, and the transaction signs for a utxo that doesnt exist over there, it's an invalid transaction. But honestly, splitting coins for BIP-110 is a pretty stupid thing to do, since it likely won't even have a spot market before the miners abandon the effort. Lot of room for error with very little chance of reward.

It'll definitely be disruptive, but it'll work out in the end. I'm not stressing over it.

Oh neat, I had not considered the double sell possibility, but I guess there would be no witness to the other fork after all Preparing for my first fork: feels so electric 😅

The correct method for securing the coins will be made clearer closer the time. I suspect there'll be more changes proposed leading up to it. I'm largely just waiting to see what the fallout is.
