I think that you are not the only one who wants this. But think about it, if you clearly understand that ether is an excellent coin and you want to include it in your portfolio, then what is the likelihood that its price will drop to $30? I think you yourself know the answer.
Of course, the crypto market is not predictable and anything can happen, but still the probability of such a price is extremely low, so I would recommend considering buying the ether already now.
