Vitalik Buterin, co-founder of the Ethereum blockchain, said more rivals to Twitter Inc. could spring up amid a push for a better social media experience.

Buterin, speaking at the Singapore FinTech Festival on Thursday, said he’s “hopeful in the next five to 10 years there’s going to be some kind of better social media platform” whether that’s “Twitter itself or whether we’ll see a big ground-swelling with alternatives -- we could even see both.”

“Elon is a very high variance actor,” Buterin said. He could make Twitter “really great” or “really terrible” -- and the latter scenario might open up “opportunities for other people to do something great.”
