One of Wall Street's biggest bulls sees blockchain playing a big role as an economic growth driver.

It still may be considered an emerging technology, but Federated Investors portfolio manager Steve Chiavarone is folding the electronic system, which records cryptocurrency transactions, into his stock market forecast.

"This is going to be one of five key technologies — along with automation, robotics, A.I. [artificial intelligence] and the Internet of things that drive this next industrial revolution," he said Friday on CNBC's "Trading Nation."

He's not letting the growing pains currently gripping the cryptocurrency market affect his bullish view.

Bitcoin, which has been referred to as the FANG stock of the crypto world, has been struggling to break $10,000 — just months after hitting a record price just shy of $20,000 last December.

In fact, Chiavarone sees FANG stocks, which include top tech names Facebook, Amazon, Netflix and Google [Alphabet], as ultimately reaping benefits from blockchain's processing power — as well as areas from health care to financials.

"A lot of investors went to bitcoin first because it was the first way to access blockchain," added Chiavarone. "Look, big banks are investing in this heavily. Bank of America boasted at Davos earlier this year that they're investing the most."
