Last week, an attempted kidnapping in Paris targeted the daughter and grandchild of a crypto entrepreneur, adding to a troubling trend of attacks on crypto figures in France. Since January 2025, three kidnapping attempts have been reported involving individuals linked to the cryptocurrency industry.
Crypto-related violence is not confined to France. Globally, crypto moguls are increasingly becoming prime targets.
This highlights the dark side of the cryptocurrency boom, where immense wealth attracts both opportunity and danger. Beyond abductions, the mysterious deaths of prominent figures have also plagued the crypto industry over the years.
Nikolai Mushegian was a well-known software engineer and cryptocurrency developer. He was one of the early contributors to the development of the MakerDAO project (now Sky), which is behind the Dai stablecoin (upgraded to Sky Dollar). Mushegian also co-founded Balancer Labs.
The 29-year-old was found dead in Puerto Rico, near the Condado Beach in San Juan, on October 28, 2022. The cause of the crypto millionaire’s death was determined to be drowning, but the circumstances surrounding it quickly sparked intense discussion due to his final cryptic social media posts.
Just days before his death, Mushegian posted alarming messages on X (formerly Twitter), suggesting he feared for his life.
“3 possible futures for me 1) suicided by CIA 2) CIA brain damage slave asset 3) worst nightmare of people who fucked with me up until now, I am sure these are the only options,” Mushegian wrote in September 2022.
The tragic nature of Mushegian’s passing also led to various conspiracy theories.
“Maybe it’s just my tin hat leaking out, but it is my opinion that Nikolai spoke truth in his tweet, and was then murdered as a lesson to anyone else who finds themselves in a similar situation,” a user posted on Reddit.
Despite this, the police found no evidence to substantiate the theory that he was intentionally harmed. It is also worth noting that Condado Beach, where the incident occurred, is known for its dangerous currents and strong waves. The beach has a history of fatal accidents. Thus, his death was officially ruled an accident.
Fernando Pérez Algaba was an Argentine businessman and crypto millionaire. He was famous for driving luxury cars and enjoyed a lavish lifestyle, which he often shared with his Instagram followers. Unfortunately, Algaba passed away in July 2023 at the age of 41.
On July 23, authorities were alerted when children playing near a stream in Ingeniero Budge, Buenos Aires Province, discovered a red suitcase containing dismembered body parts. Police examined the suitcase and found the victim’s legs and forearm inside, while the other arm was located in the stream.
Three days later, on July 26, authorities recovered the missing head and torso. An autopsy later revealed that the victim had been shot three times before being dismembered.
Local media noted that Algaba had been missing since July 18. The owner of an apartment he had rented on the outskirts of Buenos Aires reported that he had not returned the keys and was not responding to calls.
The New York Post later revealed that Algaba had received threatening messages in the week leading up to his death. He also owed large sums of money to Argentina’s tax agency. Moreover, Algaba also had some conflicts with a notorious local gang that demanded $40,000 from him.
Additionally, Algaba left a note on his phone stating that he had lost a significant amount of money in crypto investments.
“If something happens to me, everyone has been warned,” the note read.
At the time of the investigation, the police had arrested one suspect in connection with Algaba’s death. However, further details about the suspect and the progress of the investigation have not been fully disclosed.
Mircea Popescu was a Romanian-born Bitcoin maximalist and blogger. He was recognized for his early involvement in cryptocurrency and his controversial online presence. His unapologetic views on Bitcoin’s value and disdain for centralized financial systems earned him the title “The Father of Bitcoin Toxicity.”
An entrepreneur and outspoken libertarian, Popescu was very active on the Bitcoin forum Bitcointalk and launched Mpex, a Bitcoin exchange, in 2012. However, the exchange was reportedly under investigation by the US Securities and Exchange Commission (SEC).
Popescu passed away in June 2021, aged 41. He reportedly drowned while swimming off the coast of Costa Rica. It was rumored that Popescu had held over 1 million BTC at the time of his death.
“Mircea Popescu died last week. He was a thoroughly unlikeable person who taught me so much about Bitcoin. I think the thing that will stick with me is his insistence that noobs lurk for 6 months before saying anything. We’d have stronger communities if this was a tradition,” entrepreneur Riccardo Spagni posted on X.
The crypto mogul’s death marked the end of an era for one of the most divisive figures in the cryptocurrency world. His legacy continues to spark debate, with some viewing him as a pioneer and others as a polarizing character who significantly shaped Bitcoin’s early culture.
