There is a huge spike in the value of the unregulated cryptocurrencies, which are 'mined' using secret algorithms based on the blockchain technologies.
According to Forbes, the average 2017 price change of Bitcoin, Ethereum and XRP, three of the most common cryptocurrencies, is a whopping 14,409 per cent.
As per the publication, there are now nearly 1,500 crypto assets in existence, valued at an aggregate $550 billion, up 31 times since the beginning of 2017.
The list also features Joseph Lubin with crypto net worth ($1-5 billion), Changpeng Zhao ($1.1-2 billion), Cameron & Tyler Winklevoss ($900 million-1.1 billion) and Matthew Mellon ($900 million-1.1 billion).
Others in the list include Brian Armstrong, Matthew Roszak, Anthony Di Iorio, Brock Pierce, Michael Novogratz, Brendan Blumer, Dan Larimer, Valery Vavilov, Charles Hoskinson, Brad Garlinghouse, Barry Silbert, Vitalik Buterin, Tim Draper and Song Chi-Hyung.
The publication noted that given the "opaqueness" and crypto's hyper-volatility, Forbes presented the net-worth estimates in ranges.
"We based our numbers on estimated holdings of cryptocurrencies (a few provided proof), post-tax profits from trading crypto assets and stakes in crypto-related businesses, and locked in our estimates using prices on January 19, 2018," Forbes said.
It further said: "It's a near certainty that we have missed some people and that some of our estimates are wide of the mark".
Forbes has categorised the crypto rich list into five groups: Idealists, builders, opportunists, infrastructure players and establishment investors and said, "many fit into more than one category".
The minimum amount needed to make it to the list of cryptocurrency's wealthiest people is $350 million.
Interestingly, the average age of the cryptocurrency's richest people is 42 while for the Forbes 400 list of the wealthiest Americans it is as high as 67.
"The government does not consider cryptocurrencies legal tender...and will take all measures to eliminate use of these crypto assets in financing illegitimate activities or as part of the payment system," Jaitley had said.
