A ‘paranoid’ cryptocurrency millionaire drowned on a Puerto Rico beach after tweeting that he feared the CIA and Mossad were going to murder him.

Nikolai Mushegian, 29, died on October 28, hours after posting his final tweet.

The troubled young millionaire had a history of mental health problems and his family do not believe there was any foul play.

In a tweet hours before he died, he said: ‘CIA and Mossad and pedo elite are running some kind of sex trafficking entrapment blackmail ring out of Puerto Rico and Caribbean islands.

‘They are going to frame me with a laptop planted by my ex [girlfriend] who was a spy. They will torture me to death.’

However some in the cryptocurrency community in Puerto Rico are suspicious of the timing of his death.

He was discovered by a surfer in the water at Ashford Beach on October 29, fully clothed and carrying his wallet.

Brock Pierce, another cryptocurrency entrepreneur who is well known in the community, told The New York Post that he was satisfied Nikolai’s death was not suspicious after speaking to his family in Florida.

‘His mother clarified that his death had nothing to do with his [conspiracy] tweets.

‘He was a beautiful man and a child at heart. He was also an incredible visionary, I don’t call people brilliant very often but Nikolai was brilliant.

‘And brilliant people sometimes walk the edge of insanity,’ he said.

Nikolai’s family had become so concerned for his welfare that his father had gone to stay with him in Condado, Puerto Rico, where he is said to have lived in a $6million house.

The young man’s death comes at a time when the cryptocurrency industry is in flux.

FTX, the crypto trading platform, is on the brink of collapse and desperately awaiting a bailout.

It was reported that Binance had offered to prop up the platform with a cash bailout, but the company has since backed out.

Nikolai’s friends in the community were stunned by his death.

‘Yea so Nikolai is still F*****G DEAD my money is on him being murdered he was found drowned 4 hours after his riskiest tweet ever.

‘He had all year to drown randomly or be mugged, so it seems unlikely that his death was unrelated to his tweet…’ said Ameen Soleimani, the CEO of Spankchain.

One of Nikolai’s friends also told the Post that his paranoia was partly informed.

‘Some of his paranoia was based on fact.

‘He’d discover things. He knew things. Nikolai got bored a lot with the mundane of life. He’d go after things, constantly putting himself in weird positions. It wasn’t for the money.

‘He was interested in why things were the way they were and the corruption behind it.’

Police in Puerto Rico continue to investigate.
