Becoming alarming? It's been like that for decades. Back in the day, you wouldn't be able to make ANY cross-border payments because then, there was no bitcoin and payment processors like PayPal intentionally blocked off Africans including Nigerians from receiving payments for that very reason. Bitcoin came in and solve that problem but while bitcoin is a net-positive technology to any economy, it can also be used for bad. It opened to flood gates to this scammers and it's not easy as ever especially if you can do it under the radar (aka scam to reported to authorities and traced back to scammer).

We can only continue to use Bitcoin for good and hope that others do the same.
