I was promised like 250k by McAfee in BTC value.
When's the price gonna skyrocket like the last 8 times? Tell me plz time travelers.
Lol. Did McAfee call you and made a deal with you? Just like many of the members here promoting all kinds of projects and sites, John McAfee is also just promoting projects that pay right. John McAfee have shilled for many altcoin projects in the past. I don't think he would do that without any amount involved. Did you buy one of the coins that he tweeted? Don't jump into it. His words cannot cause hype anymore.
If the OP met Mcafee in personal, I would say that they had an agreement but if he just saw a Mcafee from telegram, it was a bait. John Mcafee is a celebrity and a well-known cryptocurrency promoter. He successfully promoted a large number of ICOs and I am pretty sure he will not shill anything because his name might be burned.
John Mcafee is a real crypto knowledgeable person so if the OP lose something, I think it is not anymore the concern of Mcafee.
