I used to believe the same until the recent tweets from Elon Musk shook the crypto market and pumped the dogecoin quite literally within days and weeks. I used to read these tweets in my leisure times and never took them seriously because that is the kind of image Mcafee created in the market because he was taking money and promoting shit coins/token.

I think with time now more and more influencers are coming into bitcoins like recently mrbeast, the famous youtuber, got into bitcoins and bought a big amount if I read the news right. With time that image McAfee created will change but yeah don't trust just anyone promoting coins and tokens out there, I agree.
