I don't have much knowledge about Bitcoin, I just have basic idea of Bitcoin. And I haven't started bitcoin investment yet, but I have plans to invest in bitcoin in the future, and I will hold my investment for a long time. With the rate at which Bitcoin has risen today, it seems like I missed a good opportunity. If I had started investing 1 week earlier, I would have already made a good amount of profit. However now the price of Bitcoin is very high, so I am waiting for a dumping, when I get a good dumping I will start investing.
I would like to say just correct that he is still not late but that's ofcourse if only he understands what the future holds with Bitcoin which ofcourse he has no idea at all. Bitcoin for me at this stage is still not late although many people who are scared will think that the price has gotten too high for them to buy which is probably what many other people like him did when the price went up all the other previous bull run when a new ATH was attained, I believe those same set of persons who still taught that 100k was an impossible feat would be dead suprised by now and also being regretful of not actually buying when they had the opportunity.
If I were you I would just stop thinking about anything and follow the advice given below and set a buying consistency strategy for a long period because that's the only was positivity can come to your investment and most importantly just hold this principle that no matter the weather the price of Bitcoin is always moving forward @historical facts.
Yeah no one's late to invest into Bitcoin even at this point when the price is going higher however if he's watched carefully and follow up the ongoings of this thread then his Bitcoin journey would go smoothly whenever he decides to take a bold step and join the moving train, everything you've said to him is very important, he has to think long-term and invest consistently and I believe by now he should've known about some good strategies that would help him accumulate better and if he could be patient enough to accumulate and hold for a very long period and more, like 4 years and above, he'll be making one of the best decisions in his life. Anyways, I want to also add that he should ensure he has a stable source of income that would help him accumulate consistently for long-term.
