How much time do you consider this will happen? Right after halving, few days, weeks or months?
I say months to year. It won't be an instant if that's for the price increase that we're waiting for because it will take time. I'm comparing the scene just like the 2016's. As we saw it during that year, the price rose after more than a year.
And that's the known bull run of 2017.
Actually in 2016, the price started to rise before the halving and continued a gradual increase. It did take over a year for the huge rise to $20,000 but the smaller increase began much sooner.
Remember that the starting point now is $7000 to 8000 so the rise that OP is talking about to $14,000 is not the big gain that we may see in a year.
