The whole concept of bitcoin is to be anonymous so if this can benefit that goal, why not.
Uhm, no, Bitcoin isn't anonymous in the first place, why would it be the concept?
Then read the Bitcoin white paper again, section 10 Privacy.
So if "
Privacy" is the title of Section 10, it will be the "
whole concept" of Bitcoin?
It's just showing the level of privacy gained in using this peer-to-peer currency and the options to improve it.
If we're going through sections, I'd go for the "
introduction" and "
conclusion" for the concept.
BTW, I'm not with those who said that "
CoinJoin or mixing are useless".
