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
