I know ETH is a new generation of BTC vid, which has some finishing and more easy to use functions.
It has not relationship with bitcoin and i could say that it's really different with bitcoin. as you can see that how it was using the different algo and blockchain structure although it was using the bitcoin source code as the basic code but it's really different with bitcoin, i hope you can try to learn more about that before try to say anything about that. it's really sensitive.
