Trusted teacher: Since 2010, the surveillance technologies of large companies as well as governments have considerably increased. Although you do not use any Google product and "refuse cookies", Google Analytics trackers are present on 90% of the websites and the sites you visit know your age, your browsing history as well as what time. you chat on WhatsApp, with whom and how often. These trackers form your digital footprint, in spite of you, and sell them. Your insurance, for example, can tell if you are expecting a baby in 9 months or if you develop signs of a chronic illness. I propose to teach you to: - Configure your phone and computer to use the Tor network, and protect yourself against surveillance. - How to use a VPN, which protocol to use and how to check if the VPN is monitoring you. - How to set up a kill switch so that the VPN does not leak and that the internet only works when the vpn is connected. - How to use a different operating system to stop monitoring Apple, Google and Microsoft. - How to pay on sites anonymously by purchasing prepaid credit cards with bitcoin. - How to anonymize your bitcoin - How to ensure that the government cannot afford to find you. - How to register on websites anonymously. - Buy Bitcoins (or other virtual currency) securely and anonymize them. I have worked for years with journalists, NGOs and companies to improve security and teach how to be anonymous in the eyes of big companies, malicious actors or even governments. Important: I do not teach courses on "how to make money with bitcoin", I only teach how to use it responsibly and the advanced protocols on which this system depends.

Oussama
I have no prior experience in this area and I took lessons with Ousamma. He has enough patience and a knack in guiding you step by step through the lessons and exercises in a very simple way to understand them well. He is an invested teacher that is kind and polite. He will help you to develop your abilities and to feel confident in order to achieve your goals. I warmly recommend him and extend my gratitude his great support throughout my learning journey.
