Just remember that folks.
The Bitcoin market was bullish before the two previous halvings (hence no clear correlation in my humble opinion). But if you believe there is a correlation then it's important to consider other indicators, and not the halving alone.
When you check the history of Bitcoin price, you will notice there was a clear bullish trend before the two halvings occurred.
I am in the minority here but I doubt this year will be bullish, the trend is still bearish, it has been bearish since we were rejected below 14k last summer.
Watch out for March-April, if they are still bearish months, there is no way IMO the price will skyrocket this year. The important prices here are 10.5k (very strong resistance) and 14k. Before we break these prices again there will be no uptrend.
I was keenly watching during the times of 2016 halving and I observed in no way market reacted to halving. I do call that market was stable at the times of halving rather than it was bullish still I agree that market was not under the control of bears as after the then ATH at 2013, market was in bear's control fully on 201 and on January 2015 it hit the lowest of $180 and then started to be stable and bullish/bearish in 2015 completely.
Hence, during the 2016 market was under the control of bears at the same time bulls were also not too active. End of 2016 failed to have new ATH but beginning of 2017 showed us new ATH only after the new ATH bulls entered into full action. Similarly, we may expect bears to lose control around the times of upcoming halving and by end of this year, bulls may get all the required power to get us new ATH.
