Since, 2018 after the super bull run of the crypto market the ETH price has touched $300 a minimum of 3 times yearly but never sustain above this level. So, now also you no need to be happy enough till the price never break the $400 in a medium term. If the price be stable for the longer period in around of $300 then it is most possible that the price must decline to $150 or less again.
I am also still waiting for etherium above $ 300 because the price of $ 300 often occurs in recent months and finally drops again, for now let's wait, whether etherium prices can exceed current prices or not, if in a few days there is no movement already confirmed that etherium will decreased prices again
If the $300 can sustain for a long time, it is a good sign for you to invest because I believe by the end of this year the value of this coin may soon reach $700. Based on what is happening, investors are very optimistic and this is a good opportunity to make profits. I was lucky to buy ETH at $150 and am making twice as much profit, but I have no plan to sell it because the current price is still very low.
