The increase in demand is yet to come. It's too early to assume that the demand is increasing because the halving just came in. But in the long run, we'll see that the demand will increase. Each year that's coming to bitcoin will make it harder to own 1.
Well as you can see on the bitcoin graph, the demand increased when the halving took place. That demand growth is obvious in the first look, and to consider the massive speculation for the halving 2020 it is expected to be that way, the only thing we expected but did not come is the price speculation, literally the bitcoin stays at the range that I though it would be impressively it reached the $10K mark in the month of May, then just days ago of this month. We still can't see the shortage of the supply since the demand is low, but in the future days we might able to see that.
Some are scared because of the potential that many miners will shut their equipment but if it happens, there will still be some of them that will continue to mine. I'm long and hopefully, others will hold too until you can.
Only those miners who carry low-end equipment who does not want to upgrade because of an expense is the one who will be saying goodbye.
