I would not be surprised if the price rises as a consequence of the halving, or may be some time before it. So even if the halving does not change the supply, the speculation of future price includes what others think, so if one speculator thinks it doesn't matter, he might believe that other think it matters...
To expand about what supply and demand is in the market sense, the supply is what someone has and offers for a price on the market, and the demand is what others decide they want to buy for a certain price. Taking demand as an example, it can be expressed as a vector (two numbers) the price and the amount. You see this as the meme "if it goes to 120, I'll buy more, and if it goes to 100, I'll max out my credit card and buy all the coins..." So someone, you or me, might have a plan to buy some coins, and you decide to buy 2 if you can get them for 286.41 (one dollar less then the last price on finex at this moment). Then in your life, a few economic events happened:
1) Your salary appeared on your bank statement, and you have quite a few dollars.
2) Heck, it is 500 more than you expected?? Oh, I already paid off that credit card bill of 499 a few days ago, and I forgot it. Maybe 3 coins, not two...
3) Wife: My mother just called and invited us up to their place, it is beautiful there, and I don't like those long flights and sitting on a beach for two weeks anyway, I think we should go for it. (And you think, ah, thats a few thousand saved for a vacation, I think I can buy 6).
4) Dad, my phone works again, I just had to restart it and update the apps.
5) You just saw the price climbed 2 dollars, but what the heck, I just saw a video explaining the glory of bitcoin in country X, so I just buy 8 for what is currently on offer.
The price vectors constantly change in a persons mind, and when you add vectors of the same price, and put the vectors with other prices side by side, you get something that resembles the bid curve displayed on bitcoinwisdom, except it is an unseen curve, constantly changing, the aggregate of all demand vectors for all the people on earth.
The ask curve is something like it for people who might want to sell for a certain price.
The money quantity has some significance, because the more coins exist, the more you might think is on offer, but, not true if everybody wants to hold until they can obtain a much higher price.
