Woah.. If the reasons my funds are being held is because the question of legitimacy, I am happy to provide KYC.
Everyone is going of claiming I am a criminal and my funds are of criminal origin which is just a lovely and convenient assumption.
On another note, my wallet address was never flagged, the address the 13btc were sent to was flagged by me.
If you would like to check transaction ID and see the list of my bitcoin transactions, it will become clear that my funds are not of criminal origin or gained through scamming. I purchased a majority of my coins on Coinify and the rest on OTC exchanges. Are we done attempting to distract from the obvious issue, which is that I was scammed or are we still going to go on some utterly bogus and random tangent about my source of funds?
KYC lol, KYC is just knowing who your customer is. Providing ID and doing a basic liveness test will not help you with a transaction of $600k with anyone who is complaint, maybe Mr Loyce chip mixer will happily take $600k without asking.
$600k you will need to prove proof of source of funds, cleary showing the trail money and where its from
$600k you will need to do enhanced due dilligence, background pep and sanction cheks.
Just providing ID wont suffice here.
Looking at mycryptomixer, they seem to also be rogue website offering unregulated services like Mr Loyce chipmixer, no company number, address, country of incorporation etc.
Had these been genuine companies you could go down the legal route, even then i would be difficult.
Unfortunately you gave your money to a website that doesn't even show who the owner is LOL.
Good luck buddy, but I think its safe to say you were scammed.
