I think That the Ethereum cryptocurrency at the end of 2018 can rise to the level of 1000-1500$ ,and perhaps more, we'll see.
All is subjective. And I think if the BTC rises quickly, then the ETH rise above the $ 1,000 is quite likely to happen. So wait until the bull run at the end of 2018, the bull run will definitely occur and the BTC rate is expected to rise to $ 15,000 or more.
