Mac, a crypto enthusiast in Scotland, was browsing Twitter in November when he stumbled on an enticing offer: A news account he follows called Briefly Crypto was promoting discounted gift cards, purchasable with cryptocurrency, for Black Friday. Mac—who declined to provide his last name, citing privacy concerns—decided to buy his parents some hotel vouchers for Christmas.
The link was for Bitrefill, a platform Mac was familiar with that allows users to buy gift cards with crypto. He knew the Twitter account promoting the deal, so he figured it was safe and clicked on the link. After selecting the vouchers, he connected his crypto wallet and signed off on the first transaction.
