I still fully believe in ethereum. Many ICOs work on ERC20 platfrom, powerfull smart contract DAPP. No one can replace the role of Ethererum in crypto world. Despite the price of Ethereum was down recently month but i think i can bounce back in Q4 2018. The ethereum network is so big now and it has proven the strong of ethereum. Also no one understands about crypto than Vitalik and he still working hard for improve the technology behing ETH.
