John McAfee is one of the person who gives more positivity to the crypto people. Whether the prediction is gonna come to reality or not, but whenever he comes forward with some statements I feel convinced even when the market is not that progressive. As some users mentioned he's mocking, I suggest let him mock and he isn't creating any negativity around.
He's like that because he invested so much in Bitcoin and other cryptocurrency. This is just a form of initializing a placebo effect. Saying impossible (lowly probable) thing would make people hope to see it happen. Though he's using Math or something, this is cryptocurrency and nothing has been certain since this started.
However, this kind of attitude is what the whole community need in order to make the price steadfast.
