"I’ll eat my dick on national TV if bitcoin doesn’t surpass $1 Million by the end of 2020"
_
John McAfee, whose fame exists rather heavily due to the software company he founded in the late 1980s, took to Twitter yet again on February 2, 2018, to reaffirm that he was indeed bullish on bitcoin. In an attempt to predict bitcoin’s price at the end of this decade, McAfee had previously stated that it would reach “$500,000 by the end of 2020”. In November 2017, he tweeted that the cryptocurrency had accelerated much faster than expected, causing him to raise his prediction to $1 million instead.
