Most of the people are speculating the price increase. and they can get disappointment this time. Because everyone has kept their bitcoins save and when they all start to sell, price can Dip very quickly
I think the price should stay high (at least for a long while) after the halving. If it dips suddenly then most of the investors will likely cancel their sell orders, causing it to rise again.
I should agree for the price remain high because when i start doing bitcoin the price for that time is around 200$ and now it reach to 420+$ so i can say halving my get the price increase to bitcoin. And im buying bitcoins now to save for future halving more profit i expected and also so i can invest on various programs so i can earn more money. And also i buy bitcoin to pay my transaction on my job needs.
The reason is that people want to buy some Bitcoins is that they want to make profit with it and that can takes also a long time because it needs time to rise and that can takes a long time.
You can also gamble with Bitcoin and that is becoming also popular so that is nice for Bitcoin itself.
