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?
Don't undermine the tracing system of the exchange, if they find out that you are trying to omit something on your transaction, that will flag the account for further investigation. read the bank's terms of service or ask before submitting your transactions because banks have their own way to address such issues.
But as much as possible, when you are dealing with a platform that is compliant with the regulatory board, you should be transparent to avoid future issues.
