ChangeNOW won't be good for that, check : https://changenow.io/privacy-policyBTC (dirty) ~ ChangeNOW website (No kyc, swap BTC to XMR, recieve funds on any xmr wallet) ~ Exodus wallet (you can use any other, where you can swap XMR to BTC) ~ Btc wallet (transfer funds from exodus to other wallet)
Coins should be pretty clean now.
You can use bigger amounts of wallets.
If you can do it better, let me know.
