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.
I feel it is wrong to think that someone has the prowess to be able speculate the market correctly, infact nobody has the ability to analyse the market movement correctly. Also I believe it is mostly traders and those that are looking for or waiting for a desire dips that will always go through the process of analysing the market before they start accumulating.Those that are investing in bitcoin for longer term purposes don't have this mindset of always wanting to analyse market as to know whether it is to enter or not. All one needs to know is to sort out there discretionary income, once they are able to do this the next thing is to start accumulating instead of waiting and analysing the market at the same time missing market opportunities.
