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?
