I still believe on bitcoin and I know it can make an incipient all time high this year despite of so many challenges bitcoin are facing now.I believe that the history will repeat so let's wait.
You are right the previous one was different. Situation then was not like the one today. So I think it is not easy to reach that level again in the recent months. To my knowledge it may hit $20000 after 2 or 3 years because of the normal growth in the future. Other reason is market manipulation from the big investors. They fix the limit for the price.
