I really support this idea, because it is true that the best altcoin is still ETH even though there are so many other new projects.
but it all started from the ETH network they just copied it,
No contest about ETH being the best altcoin. It never gets old and remains at the top, where smart contracts originated CMIIW.
and the copycat will never be better than the original.
So true, but there is also no contest if the copycats have made themselves well and become a good project. The outcome turns that it's got some volume because of how they worked on the project although being a copycat has got to start from somewhere and it's still inspired by ETH.
