Why do you think that this ETZ useless?
The concept is cool
It may solve big problem of zero fee and instant Tx.
I just dont get the price seems too low and no concap market info.
There is no such thing as zero fee and instant transactionn. Any protocol doing such, if true, will not be sustainable in the near future. Even then ETZ actually smells like a scam from miles away. I would avoid it like the plague or ebola.
Invest wisely boys.
