Smart Contract technology is very much used by other cryptocurrency project projects, making ethereum a lot of people and having a strong community, I believe ethereum will never die, etherum is always the best altcoin.
as pioneer in blockchain platform that give easinest for developers to create their smart contract , ethereum still unbeatable by another coins.so far there is not platform that used by most new projects.and i see for next several years ethereum still be best platform that have best community.
