Ethereum price is now below 600$. Do you think it is the best time to buy Ethereum now ?
For sure if but in that price last year it's a big problem to you that 1 Ethereum right now goes to 100$ it's a hard prediction but in this days ethereum get pumping again same as bitcoin and altcoins.
ETH will make the market and going to go up once we see some move happening in btc. And when the bull run happens all such top best coins will fly quickly as they have being dragged badly during this bear market. So keep buying till the time market is on lower side.
In any case, it was more profitable to buy Ethereum another 2 months ago, when the price reached $ 76. But in any case, even at current prices, the investment will be a conclusion, given the 2017 price level.
