  • NFTs could become "a much bigger, more fluid market" than bitcoin, "Shark Tank" investor Kevin O'Leary predicted.
  • His belief in NFTs stems from the idea that can they prove ownership of real-world items, such as designer watches or flash cars.

"Shark Tank" investor Kevin O'Leary is a big believer in non-fungible tokens — he even thinks they have a shot at becoming bigger than bitcoin.
