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.
Not at all mate we still have time for investment, for me eth spike has began with a bang and I believe it will follow up with the same momentum.
Looks like alts season has started and there are more possiblities for a big change in the market as many of the big whales have started to Invest in ETH and yes we can even Invest now and expect some good return.
