How can I guarantee anonymity of my Bitcoin transactions? Shall I use VPN or what? Now I googled Blockchain numbers and saw everything on the internet. Guys how do you deal with that?

Bitcoin is normally anonymous by nature. If you failed to notice it, you must be using some crappy exchangers. So until you enhance your trading literacy I would discourage you to continue with trading. Better come to crypto casino https://duckdice.com/promotions and buy a lottery ticket or play dice games, they are much simpler and payments are instant.
