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.
Nice thank you,
btw, as far as I know (I might be quoting them wrong), the anoncoin developers also believe that tor is a risk to be used for anonymity. Since it also hides all possible fraude. While I2P has less 'exit points' I think they called it and is therefore less prone to fraude. Why, I don't know.

. If anyone can explain in more detail or correct me, feel free.
