Bitcoin halvings which have happened before always displayed far-reaching heights, hence the same is expected of the upcoming one.
...
The times that the price has risen dramatically
do not coincide with a halving. Doesn't that indicate the price rises are unrelated to the halvings?
These facts contradict the story of the halving-induced price rises:
The price rise after the 2012 halving started about a year before the halving and ended with a bubble shortly after the halving
The rise to $1000 started six months after the 2012 halving, after a steep drop following the previous bubble. If you attribute the rise to $1000 to the halving, woulding you also attribute the fall from $200 to $70.
The price rise to $20000 started about a year before the 2016 halving and the price actually fell during the month after the halving.
You make a very good point, but we normally see a slight increase in the price about a week or two before the Halving event starts and that might be directly attributed to the media hype that are built before the event happens.
I think people give more credit than credit are due for this event having a significant impact on the price. The impact is much smaller and it only last about 2 or 3 weeks.
