The dispute over the authenticity of Satoshi Nakamoto caused by $5 billion: Dave Kleiman is a warrior facing a bleak life

In the past two days, Craig Wright, the Australian "Satoshi Nakamoto", has been making trouble again. First, an old article in which he claimed to be the founder of Bitcoin a few years ago was dug up again, and major platforms have been rehashing it. Then, he was sued by the family of his former partner Kleiman, who accused him of property embezzlement and stealing Bitcoin worth $5 billion. As soon as the news came out, the saying that "Kleiman is the real Satoshi Nakamoto" began to spread everywhere. It is worth noting that Kleiman died in April 2013. In the hot wave of "Who is Satoshi Nakamoto" that year, a Japanese named "Dorian Nakamoto" appeared who was very consistent with the identity of Satoshi Nakamoto. Satoshi Nakamoto, who had disappeared for three years, appeared in 2014 and said his last words: "I am not Dorian Nakamoto."

Regardless of whether Kleiman is the real Satoshi Nakamoto, his life is worth watching. This is a story without Craig Wright.

"Two weeks before he died, there was a big change in his mood," Kleiman's friend Paige recalled. The formerly generous and active computer expert became irritable and bitter. During that time, Kleiman left the Veterans Hospital, and Paige happily said to Kleiman: "They let you go? That's great!" Kleiman said: "No, I told them to get out of here!"

Dave Kleiman is an Army veteran, computer expert, and occasional national radio interviewer who asks him about his expertise in computer forensics and security.

Kleiman was born in 1967 and later adopted by Louis and Regina Kleiman of Palm Beach Gardens. He showed great interest in computers at an early age. But even to his friend Paige, Kleiman's early life was a mystery.

In 1986, at the age of 19, Kleiman became a helicopter technician in the US Army. In 1990, at the age of 23, Kleiman returned from the army and began working in the Palm Beach County Sheriff's Office. Paige was Kleiman's training officer at the time, and they later founded a computer forensics company together in 2012.

"You have such strong knowledge in computers, why do you want to do this job?!" Paige once asked Kleiman. In the 1990s, personal computers were undergoing a revolution, and with Kleiman's talents, he could definitely find a job that paid more than the sheriff's office. Kleiman said that working in law enforcement was his ideal job.

In 1995, Kleiman suffered a great change. In a motorcycle accident, Kleiman was disabled and had to spend the rest of his life in a wheelchair. However, everything has its two sides. This accident actually strengthened Kleiman's interest and achievements in computers. After that, he still stayed in the sheriff's office, working in computer forensics, until he left and became a freelancer.

After the accident, his father said: "My son is an extremely strong person. Even though he is in a wheelchair, nothing can stop him."

Over the years, Kleiman's reputation as a computer expert has grown. He began to appear on CNN and ABC News, and co-authored the Perfect Password, a book on computer security. When it comes to security, Paige said Kleiman is extremely persistent, and he has seen Kleiman enter a password of about 40-50 characters when accessing his files or devices!

Around 2000, Kleiman began researching computer and email security issues.

In late 2010, a friend went to visit Kleiman at his home and found him fallen in the shower and unable to get up. The friend called for help, and Kleiman was taken to a nearby hospital. For the rest of his life, he would only leave the medical center occasionally because of infectious diseases, usually to assist Conrad and Paige with their work. Otherwise, the two would bring the CD to Kleiman during their visits. Kleiman was a paranoid workaholic. He had undergone several surgeries in the hospital, and after each operation, he couldn't wait to get back to his computer.

Kleiman returned from the hospital in 2013 and entered what Paige called his "period of rage." He hid in his home, refusing to see visitors, even close friends. He was sick, and at one point he told Paige he was shaking and trying very hard not to have a fever. But later, he called Paige and said if she called him again, he would call the police. Kleiman was caught in a paradoxical state of anxiety in his final days.

Less than a month later, Kleiman was found dead in his home. According to a report provided by the Palm Beach County Medical Examiner's Office, Kleiman's death was horrific: his body had begun to decompose, and there were traces of blood and feces on his wheelchair, with an open bottle of wine and a loaded handgun next to it. Bullet holes in his mattress seemed to suggest suicide or foul play, but no bullet casings were found, meaning he may have cleaned it before dying. The official cause of death was listed as natural causes, and Conrad said it was possible that the MRSA virus stopped his heartbeat.

In this way, the 46-year-old Kleiman has gone through a rough life. He has been married twice, divorced twice, and has no children. In 2018, it has been five years since his death. Does it matter whether he is Satoshi Nakamoto? After reading about his life, a life of struggle, no matter what, he deserves respect.
