From the charts I've seen from past Bitcoin halving events, it takes about 6 or so months for it to really start picking up. We're already starting to see the effects on what the halving has done to miners. Check out this link below.
Miners profits are down almost 50%. It makes sense since they are now getting half the bitcoin from the same work. Miners are were new Bitcoins are created. I don't think they are going to sell for a loss. We'll have to see the price of Bitcoin at least his $14k-$15k before miners are willing to sell again, maybe more. Either way I feel holding on to Bitcoin long term will be the best play.
I agree with @NazarV03 price will hit at least $50k by 2021. Time will tell ☺️
