Different sorts of phone scams are pretty popular in my country, but I've never heard of any that involve cryptocurrencies. I find it hard to understand why people would believe they need to transfer their BTC anywhere to solve social security issues. It's easier to believe these things when it comes to fiat, but why would official charge anything not in the official currency? $2M is a significant amount of money. I am sorry people lost that much. I hope it will be possible to track these scammers down. After all, phone calls are traceable at least to a certain extent, right?
Thanks for sharing important info, op.
Yes, a lot of phone/sms scams have been popular in my country as well. They will send you sms saying that you won this xxx,xxx amount but before you can claim it, you have to deposit something. And many still fall for that kind of trap and those scammers take millions of dollars to unsuspecting victim up to this day.
I don't know if they can track them though, usually they will just buy pre-paid sim cards and once they've scammed people, they disposed the sim card and buy a new one to continue. So everyone needs to be very careful specially in cryptosphere.
