Dark is a joke, its not even anon. DRK is th enew FTC.
it went, FTC --->QRK---->DOGE---->Blackcoin---->DRK----???this is the dump cycle.
Anoncoin seems to be much better.
Bitcoin is not anonymous in the least. It's more open and transparent than Paypal.
Even if you tried to hide your tracks through mixing, there's a very high possibility that you would recieve tainted coins(your own coins sent back to you), and that would unveil your tracks....
Not to mention, as I type, there are people designing programs to follow every transaction a Bitcoin address has had and will make, that would obliterate any kind of privacy one can hope to attain through mixers..
how do people even know I own which coins in the first place....!
Any exchange you used know which coins you own. Any individual you do trades with know which coins you own, etc etc.
So if one never used and exchange or never met anyone to buy btc, cash only deposits into a bank account, no ID. you are good to go.
