John McAfee, the former antivirus software pioneer whose adventures include being accused of murder, has let it be known that he's charging $105,000 per tweet promoting a cryptocurrency or an initial coin offering (ICO).
Using his lucrative Twitter account, the self-proclaimed "crypto visionary" tweeted to his 811,000 followers a link to The McCafee Cryto Team website on how his promotional tweets work.
"Within the cryptocurrency industry, nothing can match the power of a McAfee tweet," the page reads.
"Frequently, a single tweet has resulted in more than a million dollars of investment into an ICO, and multiple currencies have increased more than 100 percent in price from a single tweet."
An ICO allows potential buyers to invest in a cryptocurrency before launch.
ICOs are used to help fund the development of a new currency.
