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.
It is a fair assessment as the price of ETH has moved a lot higher from the bottom we saw when the entire market went down and i remember collecting a few coins when the price was around $50 and now the price has gone above $300 and i am not comfortable entering the market right now as the market and move in either direction and i do not want to take any unwanted risk considering that the upgrade was extended.
