Will selling the fork coins to an exchange link those forkcoin utxos to your real btc utxos?

Great point. View quoted note →

yes

So have to put em through a mixer before selling?

If you coinjoined/mixed them, the exchange likely would freeze your funds if you sent them there. Also, sending them to an exchange would still dox that you own them regardless if they were mixed.

Before and after

But there will be no exchange to even do this 🤣😂🤣🤡 there is no hashrate or at least no BIP91 (MASF)to even solve current 133T network difficulty and sustain it for 10 min. Legacy chain will keep going Remember when they fork off difficult does not change no matter how much hashrate they can gather it will still be in trillions until difficulty adjustment in 2016 blocks

This assumes Bitcoin Luke’s Vision coins will be worth anything at all, doesn’t it?

There's a MASF in BIP110. It's the first activation condition.

Mixing the fork coins? With what?

yes
