We can't know i the next few months it could go lower, I wouldn't rule it out, but we are definitely in a clear buy zone if you plan to hold bitcoin for the long term.
We do not even know if the price by the end of this year will be lesser than $15000, bear market can last like that if 2018 that started in January and last long all through the year, that is just it. I understand that it is a buying zone, because people that buy now and hold for like 3 years will make significant profit, I agree with this.
