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.
Next year will become the right time to buy eth, in many strategy next year is the best. January - February 2019 market will show the right move, will go up or down again. This is not the best prediction I have but at lest I have wise calculation and money management to face risk. Buy now is fine but I believe this is correction, trust me.
