Abu Dhabi state fund Mubadala said that it was not a crypto skeptic with optimism on investments in related infrastructure. 

Abu Dhabi's Mubadala has invested in crypto-related infrastructure, according to its chief executive Khaldoon al-Mubarak in a recent «CNBC» interview.

«From our perspective, I think we look at the ecosystem around crypto,» Mubarak said, citing examples such as blockchain technology or energy usage. 

«And I think we are investing in that ecosystem.»

Not Skeptics

Mubadala’s Mubarak noted the phenomenal surge in the crypto market’s value as reason for continued bullishness in digital currency’s future.

«I think, you know, this is a business that had, what $200 billion worth of crypto value two years ago, and it's two and a half trillion dollars today and growing,» he said. «So I think while many people are skeptics, I don't fall in that category.»

Mubadala currently has $243 billion in assets.
