Bitcoin halving combined with this bitcoin price halving will surely leads to greater rise in price
Less bitcoin earned by miners --> Price of bitcoin is less --> Miners refuse to sell at loss --> Lower seller means buy pressure is high --> Buy pressure is high means price is high
You are an advance thinker but as what I notice to the market, they have similarities but the didn't work like that at all because miners are doing their job to earn a profit and we cannot say whether they are going to hold or sell as they are free on what they are going to do to their earnings.
And with regards to price increase it will come from demand usually, though you have a point that the price will increase if the seller will be less and the buyer will keep on coming. But these scenario can be easily altered by big whales as they control most of the supply but with regards to the upcoming halving I also believe that the bitcoin price will continue to increase until we hit the bitcoin halving.
