This makes all the chain analysis companies and the armchair blockchain sleuths simply follow transactions on the bitcoin blockchain forever, thinking they are doing something productive with their lives, while you have hopped over to another chain that they can't track assuming they even noticed that you swapped.
That was a viable last decade solution and is unfortunately centralized, this decade in 2020 you can also use the decentralized renBTC to permissionlessly lock up and mint your bitcoin as an erc20 token on the Ethereum blockchain. So now you are really liquid and have access to the entire decentralized finance economy.
But again, if you really want to get government bucks and an unlinked trail, you need to sell the renBTC token for Ether and move that Ether into either Tornado.cash for a little while, or go back to the centralized solution like Morphtoken and swap the Ether for XMR as XMR has an inherently stronger anonymity set than anything else.
Peace.
