Billionaire investor Mark Cuban and Kevin O'Leary, well-known from "Shark Tank," have differing views on the meme cryptocurrency Dogecoin (CRYPTO: DOGE). Cuban, also a minority owner of the Dallas Mavericks, has been a strong advocate for Dogecoin, leveraging his influence and social media platform to promote the coin. In February 2021, during a surge in Dogecoin's value, Cuban expressed his preference for the cryptocurrency over a lottery ticket. The Dallas Mavericks, previously mainly owned by Cuban, began accepting Dogecoin as payment earlier that year. Cuban's support for Dogecoin contrasts with O'Leary's stance, showcasing their differing perspectives on the digital currency.
