Right after the first halving in 2012, the Bitcoin price rose from $12 to $140.
It didn't happen until well into the following year.
I expect nothing much until 2021 myself but I'm more than willing to be surprised. I think this one will be significant in that inflation will finally fall below the average competently managed fiat currency and it'll gradually dawn on people that there really aren't that many more coins to come.
Good analysis. Similar to wait is laid out in the video as well. Price should trade sideways slightly up into $11,400 and the increase in price should not occur until 6-18 months after the halving. Of course this is only based off of the last two halving cycles we have to go off of but nevertheless the base case.
