Recently we witnessed another all time high in the price of BTC where value was above the $11,000 mark before a drop to around $9,200, Should we expect another ATH around $15,000 before the year runs out?
It's absolutely bananas to me that bitcoin answered your question within a week; whenever bitcoin does big price jumps like this everyone starts to get nervous, a few people sell of their coin, the price goes down for a little bit... but all in all it just keeps climbing, pushing past all resistance.
It's useless for me to answer your question, since hindsight is 20/20 and we now know it indeed does hit $15,000 before 2017 ends. Now I wonder if we can break $20,000 or perhaps go below $10,000 again before years end. Bitcoin's volatility has shown us that it "has no chill", it will take us for a wild ride, but always puts us back down as gently as a loving mother.

I wonder if there is any close correlation between when bitcoin spikes and the prices of the big alt-coins..
