Getting a blockchain professional is not cheap. The hourly pay rate ranges from $50 to more than $200.
Chris Barber, 39, who previously worked at an engineering firm as a project manager but for the past year has been working as a blockchain consultant, charges $225 an hour.
"I thought this was a great opportunity to reinvent my career. I started charging $50/hour then due to high interest I increased my rate," Barber told CNBC.
Barber is currently working with a man in Dubai who wants to build a short-term rental market replacement using blockchain. He is in the process of creating a smart contract code to support this idea.
LinkedIn has also seen a rise in bitcoin-related posts on its site as well as more people mentioning their skills in the emerging technology on their profiles.
LinkedIn says there are now 28 times as many people citing cryptocurrency skills on their profiles and 5.5 times as many people with bitcoin skills as there were in October 2013.
And from 2014 to 2017, LinkedIn has seen a 9.4-time increase in bitcoin-related postings within the financial services and insurance industry sector, as well as a 4.6-time increase for the software technology industry.
Experts say the surge in the price of bitcoin has played an instrumental role in raising the level of interest. Coinbase, a digital currency exchange and the largest private company in the cryptocurrency industry with a reported valuation of $1 billion, doubled its headcount in 2017 to 200 employees.
Last year the price of bitcoin soared more than 1,200 percent, to nearly $20,000. But it has since traded down to around $13,000.
Still, some prominent money managers, such as Bill Miller, have invested in digital currencies. And what was once considered a fringe phenomenon also got a bigger dose of legitimacy late last year when major derivatives exchanges introduced bitcoin futures, products that attract professional traders into the sector.
Bitcoin's price dropped a few years ago after one of the biggest exchanges was hacked and $460 million was stolen. The fear of new hacks could force another wave of negative sentiment and a selloff, says Paul Puey, the CEO of Edge, a firm that designs secure blockchain applications.
"Of course this would depend on unforeseen events," he said. But the growth of other exchanges and services around blockchain and digital currencies should blunt any negative consequences, he added.
"Fortunately this year we have a much much larger ecosystem of exchanges and services compared to 2013/2014, hence why even having Coinbase get compromised wouldn't have as drastic of an [effect]," Puey said. "And as usual, after every 'correction' is another minimum 10x price ramp. This could easily happen by end of this year or early next year."
