But 2024 has not yet come to an end (why is NYDIG in a hurry?), which means that the results of the report will still change.
NYDIG released this report now to account for its investors and show the profitability of bitcoin? Are they afraid that the 
BTC-rate may fall before the end and the reports will not be so "
beautiful"? 

Obviously, the report starts with "year to date" to give a picture of whats happening so far. This is called regular reporting; some reports come weekly, monthly, or quarterly, and these are considered consolidated reports if they have previous data as well.
I'm not sure we'll see a new ATH by the end of the year, but it will definitely happen one day (2025?).
Bitcoin's all-time high (ATH) is $73,835, and this year weve already touched $70k. So, another bullish movement could likely break that current ATH. With two months left in the year, it seems like it could happen!

That's a false belief, you cannot just believe in one investment without considering the data first. Maybe at the early stage where we still have few data but now that we have different sources, reading them especially on the bullish reports will make us confident more investing in bitcoin. 
There is no need to convince anyone, because those who need it will buy it without your advice.
Not everyone is familiar with Bitcoin, so if they dont hear about it from someone or in the news, they wouldnt know theres an investment opportunity. Honestly, I have a lot of friends who are interested in investing in Bitcoin, and since I have some knowledge about it, I can educate them a bit -at least on the basics. And I would never just tell them to buy without sharing insights that could help them make an informed decision. I want to ensure they don't blindly follow their interests or others' advice without understanding what they're getting into.
In case of unsuccessful investments (for example, they were subjected to mass panic and sold bitcoin at a loss) on your advice, they will blame you for the failure.
Nah, I see what you mean. Advising doesnt mean just telling them to buy; its about sharing the benefits, like the potential for profitability, while also educating them on the risks involved. Once they understand the basics of investing, theyll recognize that the value can drop, just like in the stock market.
If people ask me how to educate them, I definitely wouldnt tell them that Bitcoin guarantees profit. Instead, Id emphasize that while it has the potential for high returns, it also comes with significant risks. Its crucial for them to do their own research and be prepared for volatility.
