Gandeloft, who was scammed and narrated his ordeal on Reddit, wanted to convert his BTC worth  $1677. While scouting for a buyer on HodlHodl, he met a buyer offering 1650 Euro, equivalent to $1848. What the buyer wanted to pay was more than the market rate at the moment because of BTC’s sudden drop.

The buyer, however, said he was going to use the Revolut app to make payment and required Gandeloft to send his number for him to perform the transaction. Gandeloft afterward got an SMS purportedly from Revolut confirming payment of 1650 Euro with “Sam BTC” as the reference.
