I like to learn new things McAfee opened my eyes to plenty of things I suspected but had little factual basis to go on.
He explains that blockchain is insecure and also that most of your smart phones are now infected with a virus that will eventually steal your $$.
I dont own a smart phone because I was suspect that that they are not secure because they are carried everywhere a person goes. John has first hand knowledge of all these aspects of security and is able to share it with us in a non technical way that I can usually understand.
If you are interested in NOT losing $$ The video is very informative!
I still research and study many hrs a week and enjoy sharing things I believe may be useful.
I hope that you find this post useful and informative.
