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.
Such things will only waste your own time if you have the intention to invest in Bitcoin from now on, because you don't need to doubt your own intentions, especially if you intend to run a long-term investment with a higher profit target so you don't need to focus on short-term profits like you said. So it's a good idea for you to start immediately even though the price of Bitcoin is in a high range, but that is not a reason that can discourage you from doing it, because Bitcoin could pass the price of $100K and could even reach the price of $200K in the future. Now you just need to strengthen your own will and mentality not to be afraid to invest in Bitcoin before entering the new year.
