I have seen that people in deep web that use "diffrent" meathods for bitcoin trading. So how anonymus is the regular bitcoin that most of us that have it in their wallets? What is the diffrence and what exactly are people in deep web doing to trade their bitcoins?
It's not anonymous , It's pseudonymous so It can be tracked using some tools (or a combination of them).
If you really care about your privacy then you should use HD wallets (generates a new address each time you want to receive funds) and you should also use mixers (most known and legit is Bitmixer.io). See more here :
