People who are holding ETH are expecting the price of ETH will surely cross the value of 1000$ and we don't have any doubt about it but at the same time, the price of bitcoin should cross more than its previous value. So we should stay strong in the market until our desired target is reached.
Yep, the price of bitcoin must increase too if ethereum price want increase. Usually when bitcoin price, ethereum price and other altcoins price will following.
$1000 for ethereum is possible but i'm not sure is it will happen in this year or not.
