Seeing this question I was trying to wonder what the meaning of anonymous really is, to be anonymous is for something or someone to be unknown. If you are now saying that bitcoin is unknown I will like to ask further which aspect is it the originator or your address. Now I will say it's you that determine if you want your bitcoin to be anonymous or not.
After all, it's not a big problem, don't worry too much about Bitcoin being anonymous or not, what's clear here is that we must still be able to maintain security when transacting and avoid fraudulent/scams things. Just use the existing system and take advantage of sophisticated technology as a driver of our progress in terms of transactions or improve financial conditions, sometimes we can be said to be anonymous, and sometimes is not.
