Ethereum would continue growing stronger as its peak would emerge at the end of 2022 or early 2023. So, what youre looking now on coinmarketcap (ETH price) is still very cheap and i don't think we can find 3k or 5k in the near future, so just keep buying as much as you can and you will not regret it.
Yeah, $3,256 price of Ethereum is still cheap ha ha 
I think you missed the price of ETH in 2019 before the Bitcoin bull run cause by the halving.
What we are seeing this time is not cheap and since this is starting to bull run that looks like following the trend of Bitcoin again.
I am not expecting too much about Ethereum this year but $4,374 is enough a sign of a bull run and I think that's the final ATH of ETH this year. The $5k you are expecting won't happen yet and it might take some time before the bull run starts again.
