You can never be 100% but still, there are some tips to hide your identity.
Always use a virtual machine to be anonymous, you can install an ISO on Virtual Box, use VPS, etc . . .
NO LOGS VPN
If you want to be anonymous the most important thing is to use a VPN without logs. If you want to be anonymous Online I recommend you a VPN like ExpressVPN, CyberGhost, Private Internet Access, ProtonVPN, IPVanish, VyprVPN (In my opinion, these are the best ones)
You also must use an anonymous browser, when I say this I don’t mean going into incognito mode, but yes to use a real anonymous browser, for that you can use TOR Browser,
If you want to be anonymous on the internet you shouldn’t trust emails like Gmail, Outlook, or Hotmail, but yes you should trust emails Like ProtonMail or even better Tutanota, since they don’t give your information or read your emails
ANONYMOUS SEARCH ENGINE
You should also use an anonymous search engine, since we all know that Google sees what we searching on the internet, for that I recommend you use DuckDuckGo
This is also one of the most important things to stay anonymous on the internet, if you trying to stay anonymous you going to need to use a fake credit card, address, name, etc.. (we has posted some methods to get VCC (Valid credit card) and in future, we will upload more on hacksnation.com)
For fake information, You can search “Fake Information Generator” on search engines and you will find a lot of Websites that generate fake information for you, like name, address, age, gender, etc . . . .
