Privacy is not stressed enough in crypto world! Every information is made public. No real working app can be built until the privacy problem is solved!
Well, I could say that in bitcoin system there is no need to show our private information and only basic information are needed when we are doing transaction. It only contains basic information about the transactions that we are making. However, it is much better that we have a privacy so we can do much secured and safer ourselves. We can be much enjoy this system without any fear that someone can do foolish and scamming things to us.
