Bitcoin technology is not completely anonymous but rather pseudo-anonymous, since absolutely all transactions made through Bitcoin can be tracked through the Blockchain.

In addition, the balances of each of the Bitcoin accounts, the only thing that is not known is who these accounts belong to unless they make them public or known.

It is very similar to an email which if it does not include the name you do not know directly to whom it belongs.

For Example: An hotmail account you don’t know who it belongs to unless the owner tells you that this account belongs to him, the same thing happens with Bitcoin addresses.
