It's too late in my opinion. It has already been changed over 30% within the week if I'm correct and having an entry is way more risky as at any point it may get dumped. BTC on rise too and if BTC falls, alts will follow too. I think we should wait more for an entry to ETH.
30% is far from 100% or even more, so its not appropriate to say it's "too late", as if it would fall once you bought eth now.
I have eth hodling way back 80$ and it's great to see it climb up till now. Let's see how far it can reach.
