Release source code
Get eth sources and comments some strings - ok we get ETZ.
Main (or not main or ..) developer download books about blockchain developing on his github - his need know how this work and how rename eth to etz? Or how change fee from >0 to 0?
All etz developers need go to school and learn about how programming web and blockchain projects!
Why etherzero.org have old info? Developers dont know how edit html files?
While kids try learn programming guide and make new bugs for GETH official eth client - this will be considered a SCAM. And no one exchange does not want to include this scam coin wallets, while this SCAM dont have good programmers who make good secure code.
