ETH is still stable above $ 300, and I believe it is excellent. If this price level is to be stable and lasted, I believe the price will continue to go up in the future.
The current market is going to moon, so all the altcoins are going to moon on upcoming months. But we can't predict the upcoming growth of Ethereum because Bitcoin will grow rapidly on recent days so many altcoins or follow the way. I hope we see 500 USD on end of the year so many investors are buy and hold for long term.
I am also waiting for this price to appear because Ethereum has fallen for so long over the past 2 years and this is the time when the coin is rising. I am sure you will not be disappointed when investing in ETH because the value of ETH has skyrocketed over the past few days. However, you should set the price to sell after buying because the market will soon have a new adjustment.
