ETH is far from a scam. To me, ETH is the chain with the best investors, team and tech, even with the scaling issues. Just check out the solid ICOs (forget about the obvious scams, these are expected in such decentralised techs) like Arcblock, and you will see that ETH is actually the strongest coin out there.
I'm absolutely agree with you because ETH is the most highly technological coin nowadays.
Do you mean other is not high technology like etherium nowdays? How about bitcoin blockchain?
I know etherium is the first smart contract based technology but i dont think its the best technology compare with other.
But i can say etherium is the best altcoin so far because of the supporter is very big.
