McAfee began his war on HitBTC last week, when, without clear provocation, he called for a boycott on the Hong Kong-based exchange, which has more than $270 million in daily trading volume.

"The crypto exchanges have become the thing that we have originally fought against. Their power is immense. Hitbtc, for example, has increased suffering for millions of poor people who cannot afford the minimum buy-in since it is greater than their monthly income," he tweeted. "Boycott them."

McAfee seems to be referring to the withdrawal fees that HitBTC, like virtually all other exchanges, charge when customers remove assets from the platform, though his tweets are tellingly vague about the precise nature of his grievance.

The provocateur, who claims to have recently been the victim of a failed assassination attempt, continued his verbal assault throughout the weekend, vowing to be HitBTC's "worst enemy" until the company takes unspecified steps to address the unspecified issue.
