For those that earned money via DEX, with no source of funds, how did you cash out?

Let's say you deposited 100$ and then you grew that money to 1 million trading meme coins, starting your own crypto project, or something of the sort. When you finally cashed out, how did you do it and how did you pass AML and prove source of funds?

This questiom in particular is for those who live in the EU but keen to hear other stories.

I've earned close to 7 figures from projects and trading. I must have over a million transactions, this is all legal, no rugs or anything. However I have huge anxiety and can't easily prove source of funds to banks. How did you do it?

I know about Dubai, so not there.
