A man was duped out of over $550,000 worth of bitcoin by a scammer impersonating Elon Musk on Twitter. Scammers responded to Musk's tweet "Dojo 4 Doge" on February 24 with links to a fake giveaway, according to a BBC article. The links led to a professional-looking website that advertised a deal in which people could submit Musk BTC in exchange for twice as much. The giveaway was allegedly organised by Tesla's marketing department.
