No. Halving is well known about and is fully priced in. Any pump is not due to halving. Pump is either from whales initiating a pump and retail market following through or from the price simply continuing to correct back from the pandemic panic dump, or really more likely simply from the natural occurrence of the market pushing on a big resistance zone until it broke and then as what often happens if shoots up afterwards, then corrects downwards - that is an exact description of what happened the past two days. The market is not suddenly hearing about the halving two weeks before it occurs, it is an extremely well known event.
Nothing is priced in until it actually happens. Every fifth post in my Twitter feed mentions the halving. Bloomberg and CNBC are talking about it. It's definitely being hyped. If nothing else, then the surge in longs can partly be attributed to it. Plenty of people are speculating on a price rise after halving.
You're probably right that whales initiated a pump and retail followed, but that's just one angle. The narrative of the halving also plays a role. So does the tight correlation with the stock market. So do the technicals.
I don't think the bolded is remotely accurate. Of course news can be priced in. The halving has been talking about for a very long time now, everyone in the market is aware it's coming. If nobody knew about it and then someone this week stumbled upon the halving in the code and the news spread and the market pumped then yeah sure that would be an obvious reason for a pump, but obviously that isn't the case. The halving as news is well baked in to the current price. There might be whales initiating pumps or dumps around the halving just because everyone is speculating what is going to happen so whales might play into that to create extra volatility and therefore profits. But the halving isn't suddenly making news that would drive up the price like that. And the halving as an actual event (not as a news story) is a non-event really, as its effects will be felt over the course of many months to come.
If the halving wasn't priced in until it occurs then the day of the halving we should see a huge pump that makes this look tiny. Of course, as explained above, that's not how things work.
Now, just to be clear, I'm not saying the halving narrative isn't playing any role. Sure people are excited about a rising price coming into this halving, but considering everyone already knows about it, no, the halving did not cause a 20% one-day spike in Bitcoin two weeks out from the event. There are much more reasonable and better arguments, like bitcoin correcting upwards for the vastly oversold panic sell of March as well as simply that the price broke through resistance so it pumped afterwards as you would expect it to do plenty of times in that situation. I mean hell the night before it happened I figured it'd probably pump well into the 8000s if it broke through ~7800 resistance because that's just how the market works, had nothing to do with the halving.
Like you say, its multiple angles, but the halving is only a small piece of that. I was responding to a comment that tried to lay halving hype as the whole reason for the pump, when it likely didn't really have anything to do with the pump at all. Sure the overall macro environment of the market is bullish due in large part because of the halving, but that is an environment that lasts for many many months, here we are talking about a discrete one day pump not the overall recovery from the bear market of 2018.
