The price MUST go up or all these large farms will become unprofitable and shut down which would create vacum in the market. So it s inevitable, the price of a commodity this big, with such a huge demand MUST rise as soon as supply gets halved.
Nothing is certain and nothing is a must. After previous halving price of bitcoin actually went down. How exactly lack of specialized bitcoin farms will create vacuum?
It will actually be the same story imo, maybe difficulty will be lower and normal people could be mining again with profits? And you are forgetting that we already have more than 15 millions of BTC floating around.
