The blockchain is not actually anonymous. Every transaction and transfer is recorded. If you bought from someone, like coinbase, your bitcoin address will be tied to your name.
However, there are anonymizer services out there for bitcoin but it requires sending your money to an anonymizer and back to an actually anonymous address.
Just IP masking..,.?
No, I do not think you need to IP mask. The main thing is make sure none of the bitcoin transactions (money transferred) can be tied to your personal information.
Well If you buy from a site that does not need your name, Then the adres will be anonymous right ?
I am not a bitcoin expert, but I believe if none of your transactions can be tied back to you, it is anonymous. Just keep in mind that all transactions are recorded forever.
oke thx Yes I know that :D
dont worry about bitcoin, you can always use monero, thats REALLY anonymous
