What is your time frame? If you're looking for a simple speculation pay attention since you're so newbie and this world is full of sharks, whales, scammers... best time for investing depends in your wallet. if you have enough money to risk, ok go for. but if you are just going to risk your life saving and you don't have a "plan-b" it's better you avoid this chance.
I'm not investing all my life savings, and I want to be in it for the long run - so as I see it, I can buy in now, and if it drops down to 20K or something like that, it's just about keeping what I have and hopefully it will go up in the years to come.
ETH is promising some exiting changes soon, and what happens to the value is unknown, seems like miners wont be so happy with the changes they are looking into.
I feel like I don't want to miss out on this opportunity, and I'm not gonna cry about it if I loose in this, as long as the amount I invest is not everything I have. I'm super excited about it, and also what we see in crypto art and music picking up speed.
