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.
It's 3 months away. Compared to last time, we're ~ April 2016. Why do you think BTC was in a bull market then, but not now? Did you miss the 350% rally last year? And now we're re-approaching those highs.
If it looks like a duck....
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.
If you're in the minority, it's a very big minority and bull/bear sentiment is mixed. I'm seeing plenty of bear analysis in my circles and the Fear & Greed index is "fearful" at 41:
