The issue of privacy is important for Bitcoin network participants. It assures that users can exchange assets without exposing themselves.
There are many other reasons why Bitcoin is so popular nowadays, yet it has drawbacks. Data protection gives no chance for asset recovery in case of password loss. Decentralization does not allow involving any third party to resolve property conflicts. Every strong suit of the system is at the same time its weakness. One of those weaknesses is low privacy as a result of a chosen transactions system.
