Another concern I’ve been pondering — What if authorities go after anyone who bought from a KYC exchange, and the mixed their UTXOs via Wasabi, Whirlpool, or JoinMarket?
My understanding is that collaborative txns are easy to spot on-chain. And if that is made illegal, people could be in trouble for the sole act of mixing, even if the sats themselves can’t be tracked post-mix.
The Roman Sterlingov + Bitcoin Fog case comes to mind. Also the tornado cash case in ETH world.
What can we do to make collaborative txns look the same as any other txn?
