Scammers should probably search for easier targets. Crypto users have been crawling through the mud with the lowest of the low for quite some time now.
They are not targeting crypto holders directly.
Most of these scams are randomly picking victims (like the sextortion mail DdmrDdmr mentioned) but they are also giving them detailed information on how to purchase and send
BTC. I doubt those would be necessary if you target crypto users.
From the FBI warning:
Contact law enforcement before paying out blackmail and/or extortion attempts and before converting your money into cryptocurrency to pay them.
Probably most of the scammed users never touched cryptos before, but since the deal was simply
to good, or the scammers were selling stuff that was not available anywhere like ffp3 masks so they followed the instructions, bought the coins, sent them...and...
One interesting thing in the coindesk article:
So far, more than 90 percent of the scam crypto transactions were received in tether (USDT), 5 percent in bitcoin (BTC), 2 percent in ether (ETH) and a small amount in “a wide breadth” of other cryptocurrencies.
So, about time we have some talk about how "tether" is used to do...bad things more than bitcoin!
