Thank you, for the great list. I'm definitely going to try some of these services.

Good advice, but unfortunately, I can't buy a house in circular economy yet.

Tax is not a problem at all, even if I have to declare the whole amount as pure profit. My main concern is a failed SoF check, which could potentially lead to a block on my crypto.

What happens if they claim a SoF document and I fail the check?

It is true, but if this amount of cash were to suddenly appear on my account, it could raise red flags.

A crypto loan would be a similar situation, since I still need to prove the origin of the crypto in order to get the loan. I bought it with cash, so I can't provide any real proof that can fulfill a SoF check properly.

Good to see that someone with a considerable amount succeeded in cashing out without issues. Despite that, the PayPal method sounds scary to me. What can I do if they claim a SoF document while blocking my crypto and I fail to pass the check?

It's not a problem. My only concern is a failed source of funds check, which could lead to a block on my cryptocurrency.
