If I wanted to accumulate some BTC anonymously and just hold it
would this work?
Buy XMR on a KYC exchange.
Withdraw it to a Monero wallet connected by TOR or VPN
Transfer to a second Monero wallet connected by TOR or VPN
Send XMR to a non KYC exchange and buy BTC
Withdraw to BTC wallet connected by TOR
Any corrections, suggestions, or better ideas?
Why not buy Bitcoin on CEX then withdraw it to a Bitcoin mixer like Chipmixer to convert it to untraced Bitcoin before you receive it on your hardware or software wallet. That way you will remove the trace to your coin and you are accumulating Bitcoin anonymously since on your method, You still use CEX for buying XMR and just use multiple private transaction just to bought Bitcoin anonymously while you can do it with a easy short step using mixer.
