Centibillionaire Elon Musk has reacted to a joke about cracking Satoshi Nakamoto's Bitcoin wallets with a laughing emoji. 

X user @CtrlAltDwayne, who caught Musk's attention, facetiously asked Grok (Musk's popular AI chatbot) to hack Satoshi's Bitcoin riches in exchange for $200.

Musk's succinct reaction to a frivolous Bitcoin post has not gone unnoticed by members of the Bitcoin community, who are busy speculating about the centibillionaire's rekindled interest in crypto-related content. 

Will Satoshi challenge Musk?

Meanwhile, some are already speculating about Satoshi potentially dethroning Musk as the world's richest person due to Bitcoin's rapid price appreciation. 

Following the cryptocurrency's latest rally, the enigmatic Bitcoin creator managed to surpass former Alphabet President Sergey Brin. 

According to the Bloomberg Billionaires Index, Satoshi's net worth currently stands at $366 billion. Oracle CEO Larry Ellison comes in second place with $257 billion. Mark Zuckerberg is also in the top three with an estimated net worth of $247 billion. 

Musk has denied being Satoshi 

Some have speculated that Musk himself could be Satoshi due to his background in cryptography. The prominent entrepreneur cofounded X.com, which ended up becoming payments giant PayPal. As reported by U.Today, a former SpaceX intern also argued that Musk's writing style was similar to that of Satoshi. 

Musk, however, denied being Satoshi. Back in 2017, he stated that it was "not true."
