John McAfee, the founder of the software security company McAfee, claims that his entire cryptocurrency fortune has vanished. Since October 2020, the 76-year-old has been imprisoned in Spain. The US government is seeking McAfee's extradition on tax evasion accusations. He tweets words of sadness, acceptance, and anger on a regular basis. He claims to be a "millionaire who refuses to pay taxes." This claim was dismissed by a Spanish prosecutor, who labeled him a "tax rebel."
