From.my opinion you should buy the eth now. Because the price of eth is very low as compared to it's working. The best time is right now to buy a eth.
Not really low when you compare it to the recent dip when the market showing all red, the train for buying has gone, it's now all bullish market it's a goodthing but not for those who are too late to get in.
Believe it or not, from now on ETH will always increase and keeping the yearly cycle when all cryptocurrencies going up every Q3-Q4 of the year.
