After googling it, his fortune dwindled to 4 million or so at the time of his death. His widow is broke now. So the answer is that even if it was lost, the number is quite insignificant.
"What happened to John McAfee's $100-million fortune? Although John was worth more than $100 million after he resigned from antivirus company McAfee in 1994 and sold his stock, his official fortune had dwindled to an estimated $4 million at the time of his death, according to Celebrity Net Worth."
"He claimed in 2019 that he had no money and could not pay a $25-million court order over a wrongful death lawsuit. However, he was arrested the following year on U.S. charges of tax evasion, with authorities claiming he and his team had earned $11 million promoting cryptocurrencies. From prison, he told his 1 million Twitter followers he doesn’t have any hidden crypto. “I have nothing. But I regret nothing.”"
