Does someone have an idea how Anoncoin (ANC) compares to these?
They barely don't do any marketing but are developing again since recently.
I am not an Expert but will try to tell you what I was able to find out.
Anoncoin (ANC) can be used with TOR and I2P. It has quite a nice pre-built package which includes Invisible Internet Project (I2P) out of the box which is nice for beginners.
Concerning coin ownership "first features would be stealth addresses and ring signatures". I hope this helps.
