Another thing is that even if we might have an investment portfolio and we might not even invest aggressively into bitcoin, and maybe ONLY take a 1% stake into bitcoin, we still might end up with a good portfolio, but that is not guaranteed either, and I tend to recommend a starting out range of anywhere between 1% to 25% for a newbie into bitcoin, yet they still have to decide their allocation amount and their strategies in regards to how they get there.. if they might be starting from zero in BTC and then trying to figure out how they might get to their chosen allocation/target level, and are they going to lump sum into it? or maybe they will take one or two years to get to their target level, or maybe longer than 1-2 years.. depending on how much they might have in other investments (and how liquid might be those other investments).
I agree with you, sir, for a beginner 25% or at least 30% is the highest figure for investing in bitcoin, but that is also with a few notes, because usually beginners who are new to bitcoin still have doubts in them, and that is which is natural considering they are new to and just starting their journey in bitcoin investing. But for me personally, when I have fulfilled my needs, more than that I am ready to put my money in bitcoin, and of course for the long term.
Proper planning is one of the important factors in an investment, and we must think about it carefully before making a final decision. Maybe we could allocate at least 30% of our funds, but when we can only hold it for a few months, I think it's better not to do it. 1% to 10% is better as long as we are prepared to hold on for a long time.
For me, holding bitcoin must be prepared for all conditions, including conditions where we have to hold it for a long time and also for an unspecified time. And that is a sacrifice we must make.
