Sure you need to know the price history, but funny enough, for some people, knowing the price history is still not enough to keep them grounded.

So you mean to say Bitcoin won't make ATH this time around 1/1.5 years after halving?

So you're saying the past performance of a coin doesn't matter? How do you trust something without knowing how it has performed in the past?
If it wasn't for history how do we know the effect the halving has on Bitcoin price? Of course, it's not a certainty that this halving will have the same effect on price as others, but it is only because of the past that we can speculate that.
If you want to do business with someone on the forum, you'll most likely use his/her trust history, that's their past. If you want to use a service, sometimes you check the reviews.
I'm not saying Bitcoin price history is the only thing you look at, but it's going to be among the things to look at.

Bitcoin price has gone from the lowest point to a point where nobody believed it would (except the visionary, of course) and back to a very low point. A level that people doubted if it would ever recover but then again, it recovers again and shocks people, something within a very short period, other times slowly. This is what should always give a holder hope to keep holding his Bitcoin.

If you check my post history, you'll see that I always complain about high network fees because I believe that's where the real adoption starts. There's no point in the whole world accepting Bitcoin if the cost of using Bitcoin is relatively higher than its alternative. Or if you want to use a lower fee you have to wait hours, days, or even weeks.
But this post was directed at "holders".
When you're holding Bitcoin for years, you don't really care about the transaction fees. Ridiculously high network fees are a problem when you want to use Bitcoin as a currency or when you want to exchange it for fiat.

How come statistics and data from the past don't give you any idea what the performance is in the future? Even if we take a look at the average fee from the charts we could have any idea when it will have the possibility to increase its value, it might not be 100% since it is just a speculation but you still have an idea what to follow. Even not in Bitcoin, just look at some companies and ask why they keep records of the past years despite not having an assurance that it would be the same outcome in the current or next years. If you are a long-term holder of Bitcoin and don't do DCA maybe keeping an eye on the charts would not be for you since there are still traders that would have to use this data.

Nothing is guaranteed, although I understand what the OP is trying to say. As @mindrust already mentioned, past data doesn't predict the future. Yes, the historical data show that Bitcoin has been performing in approximately 4-year-old circles, but that alone cannot guarantee what's going to happen in the future. Moreover, we don't have enough data to safely say that this will also happen in 4, 8, 12 years, and so on. If we suppose that we had a history of 30-year-old data and identified that every circle runs every 4 years and the price surges to a new ATH every time, or close at least, then we could be more confident in what we could predict for the future.
I was completely disheartened when Bitcoin crashed in 2017/2018, and lost interest in cryptocurrencies. After I saw what capabilities it had, rising up to $20.000 again. in 2020, I was certain that I needed to get back on track.

Of course if you don't know about the history record of price then how do you or will analysis for trading ? Without out knowledge about price history is one kind of betting if you trading . And trading is already risky if you don't know about the history of price it will more riskier for your fund. So always when you wanna do trading in case of every coin always check the history prices specifically in case of long term trading.

Indeed, knowing the price of Bitcoin is very important for people who invest in Bitcoin, because looking at the past history and development of Bitcoin will help from a technical and fundamental perspective so that we as Bitcoin investors or especially beginners can buy BTC at the right time and sell. at the right time Of course we will watch the price of Bitcoin whether it will form a new ath or not, but what is clear is that according to the history of Bitcoin, BTC has always been

This is different from Altcoins which are sometimes very difficult to predict whether they will rise again after forming a new ATH or not because of course Altcoins are different from Bitcoin, so BTC is very good and is the number 1 crypto.

By looking at past trends, I think, to some extent, a person can predict the pattern of BTC price action in the coming month. We have seen in the past halving events that the price incrased between 1.5 to 2 years after halving, and each time the BTC price touched a new ATH. The chances are that the BTC will touch a new ATH in 2025, and we will see some short-term rallies in between. Institutional adoption is also increasing, so there are chances that we might see a new ATH earlier than expected.

If you look at the Bitcoin chart for the entire period, you can see a lot. After all, let’s say today we complain about its fall, tomorrow about its growth, etc. BUT if you look at the entire graph, it shows stable growth over the entire time. Therefore, judging from this, we can conclude that Bitcoin has made a reputation over its history as an investment-attractive asset. So it’s worth considering Bitcoin as a long-term promising asset.

You need to understand what something comes from before you can see where it is going. Otherwise you would not have any type of idea what it is at all. This isn't some mathematical stuff, this is literally history, this is basically learning what bitcoin is all about.

I understand that it may look like we are dealing with something that doesn't have the feeling that you may think it does, but that's just not how it is, that's just how bitcoin is understood. So, everyone should have some sort of understanding what it is, so that they could have some sort of understanding where it is going as well. I believe it will be a little hard, but it will definitely be the most important part if you want to become a trader.
