Your question was already answered. Stop asking the same bullshit question over and over just because you didn't get the answer you wanted to hear.

There is no such solution for BitCoin by it's very nature. Only a drastic change in the protocol and infrastructure could bring it about, and that will never happen due to the idiotic logjam that is the BitCoin Foundation and Devs.

The "It's already entrenched" excuse is no excuse. It didn't stop the Dollar from being unseated from Gold Backing, did it? There is never a good excuse to fail to fix busted shit. BTC is busted shit. But adoption is a factor of stupid people, not technical functionality.

Mixers already exist. I use bitcoinfog and have for half a decade. DarkWallet does nothing that bitcoinfog doesn't already do. It's not a solution. It's not a new idea. It doesn't provide anonymity. It helps, but it's a half-measure, at best.
