Knowing that we all suffer through this bearish trend and now we hope it's almost over it's the right time to buy ETH!
ether has a very low price at the moment because it is stable at $ 275- $ 300. That's around $ 800 3-4 months back and probably will recover soon.
Given that ATH, this should be a good price to buy a few ether because it will return some good profits.
In my own opinion, this December is the best time to buy ETH. I'm not looking on it's price/chart but rather in the Constantinople hard fork at block #7080000, which could commence roughly estimated around the 15-16th of Jan 2019, which I would love to have. Some say that this could be the end of the ethereum era, some also believe that this fork could address all the previous problems faced by ethereum which could eventually made it invincible. Choose your side whether to buy in or not but this surely be a huge price action.
