Bitcoin world domination 'a bumpy ride': Exchange CEO

Bitcoin and money

"Bitcoin is a fraction of what it could become in terms of a global asset class," Bobby Lee, co-founder and CEO of BTC China, says.

 "In terms of its value, I wouldn't worry too much about how many percent it's been up year to date because ... if you look at the five-year history of bitcoin, it literally started at zero," he said.

Bitcoin's value in U.S. dollar terms has been up more than 4,100 percent year to date. Bitcoin ended the day at $542.40.

On CNBC's " Fast Money ," Lee said that bitcoin had a big hill to climb.

"For it to be a true worldwide asset class, it would have to have a very, very large circulation value to account for the global population," he said.

Lee noted that gold, with a 170,000 tons in circulation, equals less than 1 ounce per person on earth.

"If you compare it to that, bitcoin is a fraction of what it could become in terms of a global asset class," he said. "As we get to a future utopian society, if bitcoin were really to take hold in this society, then the total circulation value would have to be in the trillions, and to get from zero to trillions is going to be a bumpy ride."

Lee admitted that there was little to stop someone from creating another digital currency but argued that the open-source bitcoin was "already way in the lead."

Regulation would likely be needed for bitcoin exchanges, he added, to prevent such instances such as the alleged disappearance of an estimated $4 million worth of bitcoin from a Chinese exchange.

"That issue is with the exchange," Lee said. "You know, it's probably run by some unscrupulous people who ran away or disappeared so far. That's why bitcoin exchanges probably need to be regulated, so that it doesn't happen again in the future."
