This isn't the first time Cuban has been burned by the crypto industry. In June 2021, he lost "enough that I wasn't happy about it" in the collapse of the Titan stablecoin. Cuban is also a defendant in a class action lawsuit related to his endorsement of Voyager, a crypto broker that collapsed in July 2022.
Billionaire crypto evangelist Mark Cuban apparently fell victim to a hack when an attacker was able to siphon around $870,000 in multiple cryptocurrencies from a wallet belonging to him. Cuban later acknowledged the hack to DL News. "They must have been watching," he said, explaining that "I'm pretty sure I downloaded a version of MetaMask with some shit in it".
