So that means, than soon we will see HUGE price increase, right? But I personally don't think that most miners sell all mined coins right away.
I suspect that there are plenty of smart miners who wait for the halving and will be able to capitalize on that event.
Exactly, when bitcoin halving happens, it will soon give a good impact to the price of bitcoin that can cause bitcoins price to rise.
So if you have many bitcoins today, then you will harvest it after the halving, if you still don't have it today, better to save and collect btc now.
