It depends on you, but I think that most would say that it's a good time because the price of Ethereum has been on a stand still recently. So, there are actually two ways to go from there; either you buy now, since it's already a good value, or wait for more time since it's value is not getting higher any time soon, or for the next couple of months. Anytime is a good time especially if you have not yet tried, If you will look into the market the value of this altcoin you want to buy
I agree, Right now is the best time to invest in our market, Ethereum is a good choice if you want to because it is cheap and it is next to bitcoin. If you have a lot of capital right now you must invest immediately. I also think like that, the price of ETH can be said to have decreased from some time ago, unfortunately this opportunity if missed
Ethereum's highest price was $1400. Now, it is only $400. If it returns to $1000, you will multiply your balance 2.5 times. So, I can say that ethereum is the best coin to invest. It is safer than many other coins
