Of course there remains the possibility of a similar situation to August 2012. This situation would take BTC on a rally to 180 and then a flatline.

However, note that this activity occured when the price of BTC was close to the all-time logarithmic trend line.
Also, November was the block reward halving event. Thus this rally was further fueled by the halving of the BTC supply.
Given the current high price of BTC relative to changes in infrastructure, as well as the deviation from the logarithmic trendline and lack of block halving, this possibility remains very unlikely.
