Taler claims to be “not a currency”, that means it has to be used with existing currency such as Euro. That means an exchange is not optional. I guess it can be used with a cryptocurrency too, or fake money, but obviously this is not what people are interested in.
And the resulting tokens are like physical cash and can not be de-anonymized by the exchange or anyone else in the chain.
Again, according to the Taler website, the exchange tracks every transaction in order to prevent double spends. If it has a full view of the network, it can employ statistical analysis.
I think you should really inform yourself better before making yourself look really stupid by confidently spreading such non-sense.
Only you make unsubstantiated claims here.
If you believe Taler is decentralized, provide an example of it being used with a widely accepted peer to peer currency such as Bitcoin.
If you believe Taler is fully private, show us a security audit which confirms Taler’s resistance to statistical analysis.
