Tim Berners-Lee called cryptocurrencies speculation and gambling

The creator of the World Wide Web called cryptocurrencies dangerous speculative tools and compared them to gambling.

Discussing the future of the World Wide Web, Berners-Lee stated that digital currencies are "just speculation."

He also made comparisons to bubbles with no substance. "It's just speculation. Obviously, it's very dangerous," Berners-Lee said in an interview with CNBC. "...if you want to have fun gambling, essentially."
