Billionaire investor Mark Cuban has praised the controversial upgrades to the Ethereum network, saying they should make it more eco-friendly and help the system's applications "dwarf" bitcoin.

Speaking on the Unchained podcast, Dallas Mavericks owner Cuban said the move to a more efficient system will mean "the holdback of the impact on the environment will change immediately."

"That is going to give some people a reason to use Ethereum as a store of value over bitcoin, right there." He predicted that Ethereum and 2 or 3 other blockchains will prove to be the "winners" in a few years' time.

"I think the applications leveraging smart contracts and extensions on Ethereum will dwarf bitcoin," he said. "That doesn't mean I'm going to sell my Bitcoin. I'm not. But at the same time, let's just say I own a lot more Ethereums than I do bitcoins."
