The FBI has issued a warning about rising work-from-home job scams involving cryptocurrency. Scammers lure victims with fake job offers, such as rating restaurants, and direct them to make crypto payments to unlock more work. Victims often see fake earnings on a sham interface but can't cash out. Red flags include jobs requiring no references and excessive use of the word "optimization" in job descriptions. With remote work's popularity surging, more are falling prey. In 2023, remote workers globally reached 28%, and crypto investment losses rose 53% to $3.94 billion. The FBI advises caution against such scams.
