I actually find this unnecessary to be updated here on before now but because I have this feelings that some persons may have been engaging on such acts as mine and Scott free may not know the penalties when it goes contrary. So as much everyone should take note be careful when you tends to help with your crypto wallets especially one of the KYCs .
No, you actually did well for sharing this happenstance of yours. I believe our people will learn one or two things on how to be safe out there. A few years ago, I also helped a distant acquittance to sell his Bitcoin but I had to interrogate him mildly to know the source of the Bitcoin. It happened that it was genuinely earned. We never can know everything and that's why we've to be careful when dealing with others as middlemen. This is the major reason I don't trade on P2P with any merchant who doesn't have "No Third Party Account" boldly written in their terms and conditions. There's even a caveat to that on Cexs P2P. I want to know real names of merchants I'm dealing with, not corporate names or those from POS machines.
Quite unfortunate for me as this incident became the second time I have got involved being interrogated and revealed to the authorities.
First was on Feb last year when my bank account was locked up and I was denied withdrawal access from my bank just after I made huge some of transaction on exchange of my Bitcoin to the fiat.
Next time, try to break huge transactions into parts and possibly don't use one account to receive the fiat. That's how I exchange whatever I think is huge. It's for two reasons I do that. The first is I don't have to trust any merchant with huge transfers and secondly, is so that banks don't get curious as to the huge payment.
