At the moment this is impossible in the market. Now the market is quite stable and sharp growth, and growth should be more than 300% is not expected. Of course, in the crypto-currency market you can expect anything at any time, but today there are not even prerequisites for the fact that Ethereum has risen in price to 1000$.
there are strong support levels at $200 and it helps eth not to drown but we can't expect so quick raise (i. e. till the end of the year).
