There is a group called Sri Lankans in UK, Lot of students are looking for ways to pay tuition fee. Check that. You can get a higher rate there :). Also if its more than 1M I would recommend you to meet inside a bank and do the transaction.
machan lot of scammers out there. But there are people who need usd like students to pay tuition fee, importers. You can sell it. If not Payoneer > Binance > P2P
I always post whenever I see this product, machan. But once I got blasted by a couple of people saying I dunno anything, so I stopped. But Good that you posted with the article, and I have seen enough of this on Reddit.
