I totally agree with you because there is no amount of knowledge a newbie we have that he or she won't be drive or shaked by market fluctuation because they are still fresh to the game.
What do you think makes someone a newbie? It's mostly ignorance or lack of deep knowledge about something, if an individual in Bitcoin investment knows all it takes to invest and hold for a very long time, guy that person is no longer a newbie, because he has all the required knowledge to succeed.
So wether a person is just starting to invest in Bitcoin or not, he will never be shaken by market fluctuation when he knows it all on how Bitcoin operate generally.
You are right. If a person has the right knowledge, the right knowledge of the strategy inside him, then he will never be afraid of the market going up and down. Since he has the ability to analyze the market completely, he can analyze it correctly with his maximum knowledge and invest correctly for a short time or a long time. Although he loses some amount of his money, he has the right knowledge and ideas to recover his money. So I think for a professional investor, no matter what the market is like, he will not be afraid of being in the market, but he can continue to invest with his own knowledge.
You don't have to be a professional to invest in Bitcoin. If you have a regular source of discretionary income and know very little, then Bitcoin is enough to start. People's knowledge and experience can vary depending on their strategy, some of them invest weekly or monthly. Excessive analysis may be detrimental to your investment, as you may want to buy Bitcoin when its price dips, but it will lead you to delayed investment and your success will never come in your favorite time. You need to practice regularly and continue to save Bitcoin regularly through patience.
If you are new to investing, you should spend time learning but as you do so you should also be in regular Bitcoin accumulation so that you can raise a decent-sized stash while you are still a beginner.
