UFC star Conor McGregor has accused retired fighter Khabib Nurmagomedov of a $4.4 million NFT fraud. The controversy arose after Nurmagomedov released NFTs inspired by the Dagestan "papakha" hat, which became famous during his UFC career. McGregor claims Nurmagomedov exploited his late father's name and Dagestan culture for profit, calling it a "disgrace" to his father's legacy. Nurmagomedov defended the NFTs as legitimate digital gifts promoting tradition and accused McGregor of attempting to tarnish his reputation post their 2018 fight. This dispute follows McGregor's own foray into cryptocurrency, where his partnership with Real World Gaming DAO to launch the "REAL" meme coin failed to meet pre-sale targets, resulting in refunds to bidders.
