A UK-based hacker just got locked up for running an elaborate crypto heist that netted millions from an American entrepreneur. The twist? He allegedly used part of the stolen digital assets to splurge on a diamond necklace for his mom.

The case highlights how crypto theft continues to attract sophisticated criminals who think blockchain anonymity will keep them safe. Spoiler alert: it didn't. Law enforcement tracked the funds and brought charges that landed him behind bars.

This incident serves as yet another reminder that stolen crypto isn't untraceable money. Investigators are getting better at following the digital breadcrumbs, and luxury purchases with ill-gotten gains tend to raise red flags pretty quickly.
