Unless a person is mixing after every transaction they perform I'd say it's no more private than Bitcoin. If the level of privacy is solely dependent on the user acting in a sane and self-serving manner then they may as well use Bitcoin. For example: Bob has 100 DRK. He uses Darksend to pre-mix these. Now he takes these 100 DRK that are in address drkaaaa0001 and goes and buys something on SilkEvolutionReloaded3 for 20 DRK. The remaining 80 DRK come back into his wallet to address drkbbbb0002. A few days later he goes and buys a coffee at StarBucks for 1 DRK. Because LEA receive feeds from our proverbial StarBucks in this thought experiment they are immediately able to see that change from an illicit transaction has been used at StarBucks, and now they have video footage and the guy's car registration number.
Thus there is a dependency on the user exercising sufficient opsec, else they will compromise themselves as they are lulled into a false sense of privacy.
hmm, interesting and worth some consideration.
so you are saying that if someone is stupid enough to send more coins than they need to a dark market, spend some of them on something illegal, then send unmixed change from the dark market back to their own wallet they compromise their privacy.
fair point I suppose, but I don't see a huge 'opsec' challenge to avoid this
