The whole point of blockchain is to track and control humanity and it doesn't take a rocket scientist or even John McAfee to point it out. It's as blatantly obvious as it can get. If people can't see that already, they are hopelessly ignorant of the facts. I recommend having a read of my previous post making this abundantly clear.
If you want to understand what kind of person McAfee is, just have a read below:

I've found documents that go back to the early 1980's discussing cryptocurrencies and digital p2p money. It's certainly been in the works. 1988 The Economist mag cover and the rest.
It's always the same MO.. Prop up a bunch of "alternative leaders" behind the scenes and send them into the truth communities to make it appear like a people's movement. This fits crypto to a T.
And beyond Bitcoin and their NSA/CIA "Satoshi" coding team, an insane number of the cryptos out there are all using Luciferian symbolism and pushing all the standard Agenda 2030 objectives like RFID chipping, food and supply chain control, big data distribution, Universal Basic Income, small living, Internet of Things, etc.
As an example, Waltonchain from China is named after none other than Charles Walton that invented the RFID chip. Ambrosus is another one of these supply chain initiatives and it is designed to support big pharma and big agra. It's not just it's one-eyed symbolism that gives it away, it's the fact that it's basically run by the UN, Nestlé, and a consortium of other very dubious interests.
Sadly, these are the standard hallmarks of many of the other key cryptos and the agenda becomes abundantly clear just by looking at these coins from a more critical perspective.
