UFC fighter Dustin Poirier's social media account was reportedly hacked to promote a cryptocurrency. The incident involved a post that was out of character for Poirier, raising concerns over the security of high-profile accounts. Poirier's wife intervened to address the scam on her own account. This highlights the vulnerability of even well-known figures to cyberattacks. Despite the hacking incident, Poirier later announced the launch of his own memecoin, $DIAMOND, on TRX, inspired by his fighting spirit.
