Let's say I took $10k from my bank account, which I earned from my job, and sent it to a mixer. After mixing the funds, I used them to invest in an altcoin. Once the altcoin’s value increased to $15k, I sold it for USDC and then cashed out at a different exchange (let's say a major well-regulated exchange like Binance).
If I provide every transaction on the blockchain from my bank account to the final exchange, except for the mixer where I can't show blockchain details, but I can show amount correlation and transaction clusters, would that be enough to get my funds released?
If I have a document prepared by crypto tax accountants and lawyers, would that speed up their process or at least force them to release my funds?
I don't understand how are you going to use a mixer and invest in an altcoin. Do you mean that you'll mix your Bitcoins, receive them in a self-custody wallet and then send Bitcoins to an instant exchange to receive altcoins? If I were you, I would directly send Bitcoins to an instant exchange like exch.cx and receive altcoins in my wallet. Once the value goes up, I would send them to Binance, convert it into USDT or USDC, then I would do a P2P trading and withdraw my money.
If you have to prepare documents and there is an involvement of lawyers, why should you risk using a mixer? If you reveal everything, then what's the point of hiding something? It will only get you in trouble. I don't think they'll like if you mention that you used a mixer.
