The only late time is later. If you are getting in now you are still in the 1% of the population who own ETH. You might be reading many posts lately about new millionaires being made and feel sad/disappointed that you "missed out". Just remember crypto is in its infancies. Could better gains have been made investing early? Sure. But hindsight is 20/20 and you're in now. This might be the only time in our lives we will see returns like this... even if youre buying now for the first time. Just be glad!
TL;DR: ETH to 5k by 2019.
I don't think it's too late, the encryption money market will continue to grow rapidly, so it's time to move into the cryptocurrency market.
