In 2023, cryptocurrency investment fraud surged to nearly $4 billion, marking it as the largest crypto scam of the year, according to an FBI report. Common scams included "confidence-enabled" schemes where fraudsters built trust with victims over time, guiding them toward fake platforms. Older individuals faced the highest losses. The rise in fraud reflects the growing targeting of investors unfamiliar with crypto technology. The FBI urges caution with unsolicited investment offers and stresses the importance of verifying platforms.
