100B is a quite huge amount of total coins, dont you think?
With all that supply, and just a clone of an already existing and established coin, I dont see that the value of this coin will be any better.
The existing and established coins you are referring to are broken and/or are no longer being supported by their devs. Thats why this is necessary. If XUN works it will be the only coin with messages, ring signatures, anonymous and untraceable transactions and blockchain deposits with interest rates.
