How do Social Media Influencers impact Cryptocurrency Prices? AMP and Bitboy Crypto

On his live stream today, Bitboy Crypto announced that he had invested $100,000 in AMP yesterday (July 25th) and that due to an increase in price he had made over $40,000. He also noted that he had made a video on July 25 telling his followers that he had invested in AMP and told his followers to invest in AMP. Is AMP's price increase connected to Bitboy Crypto's YouTube video? Nothing is certain but it might be good to keep an eye out for Bitboy's recommendation. I have posted below a chart showing AMP's price increase and a photo of Bitboy Crypto's video-- which I should note that I saw on July 25th.
