Adena Friedman, CEO of Nasdaq says positive words about Bitcoin.

"I believe that digital currencies will continue to persist...it's just a matter of how long it will take for that space to mature," Friedman said on CBNC today. "Once you look at it and say, 'do we want to provide a regulated market for this?' Certainly, Nasdaq would consider it."

On Wednesday, the Nasdaq announced a collaboration with cryptocurrency exchange Gemini who partnered with San Diego based ETF firm, Reality Shares, to launch two blockchain-related funds scheduled to come to market in June.

Eric Ervin, CEO of Reality Shares commented about this saying:"If you were to rank interest in cryptocurrency on a scale of zero to 10, Friedman would be a six, She would help get the SEC comfortable with cryptocurrency trading. She would not passively wait for them to get on board," he says. "If the SEC wanted her opinion, she would give it a thumbs up."

George Soros' $26 billion wealth management firm is planning to trade digital assets.
