When John McAfee attempted to run for the White House in 2016, he invoked a mantra from Apple co-founder Steve Jobs in his campaign video. “Here’s to the crazy ones, the misfits, the rebels, the troublemakers, the round pegs in the square holes.”

McAfee, who committed suicide in a Spanish prison last week aged 75, “fitted each of these descriptions – and more”, says the Financial Times. The pioneer of antivirus software “built and lost a fortune”, later recasting himself as “a libertarian politician” and “a cryptocurrency hype man”. In 2017, he predicted that the price of bitcoin would reach $500,000 within three years.
