Roubini, also known as Dr. Doom because he predicted the bearish market that occurred in 2007 and 2008, said in an interview that:

"The coin has nothing to do with the blockchain. Fully private, controlled, centralized, verified and authorized by a small number of nodes that are permitted. So what is crypto or blockchain? There is no. "

Reportedly, this social media giant now has several main supporters for crypto currencies that are expected to get support from many fiat currencies.

Supporters such as Uber, MasterCard and PayPal will invest around 10 million dollars in the project because of their status as part of the token management body.

Although he acknowledged the fact that the details of the project were still unknown, Roubini said that Global Coin might not use general blockchain technology such as proof-of-work or proof-of-stake. "Why is that?"

Although many people in the crypto ecosystem have condemned those who refer to Facebook coins as cryptocurrency, he denied being in the same caucus.
