Its possible to happen by next month we are almost in 250$ price of eth as of today . If they break 250 price before the end of the month then 300$ will be the next target that possibly happen next month , we just need to wait and see .
I don't see that happening next month since ETH has been staying less than $250 this past 2 months and if you look at the price history, they just followed Bitcoins movement. Unless Bitcoin were to pump next month, then we'll still be seeing below $300 in the future. Ethereum 2.0 is still faraway which is very anticipated by a lot of people which might be the way to $300.
Updates gives investors something to anticipate, some might bought more now then hold till they've reached the target, others are playing short term engagements and enjoyed the quick benefits. The market still unclear there are lots of market movements that influenced the value of this coin especially bitcoin, big pumped from bitcoin then expect that ETH and most of those alts who are tailing bitcoin will experienced the same track.
