This is the main reason why a new investor should only use part of his discretionary income that will not put stress on him to invest in bitcoin regularly with DCA method. Also the new investor needs to have a long-term committed mindset so that the price of bitcoin dipping wouldn't be his fear or concern but an opportunity for his to keep on buying consistently in order to increase and build hia bitcoin portfolio. It is only when you sell your bitcoin in rush that you will run at loss.
Reflecting on my experience in 2020, I think most beginners try to make more aggressive moves and I feel that when I try to continue to buy aggressively and try to save some needs, especially to minimize purchases that are not really necessary just because they want to buy bitcoin again and again. So with this I think when there is a beginner who does try to be in bitcoin they will not think too much about risk or even that leads to the level of stress that you said because in the end they will only keep trying to buy again and again just because they want the initial accumulation to be a little more.
Although gradually this is corrected over time but still for the initial phase in bitcoin it is possible like that so that indeed the problem of consistency or risk we do not think too far because the most important thing is to try to buy again and again even though for some people it sounds aggressive and quite naive but when someone is just starting to invest in bitcoin, actions like this must have happened at least once or maybe several times.
If you don't sell your bitcoin investment, when it is not of your will, you will not run at loss because 1btc=1btc. I think you have a trading mindset, instead of a long term investor.
For this it is true because in the end in terms of numbers they will remain the same but the average person who panics and tries to get out of bitcoin is only because their focus is on the value of bitcoin conversion to fiat so that not a few people fail because indeed their calm factor is a little disturbed, this is realized or not is a situation that actually occurs because of a lack of confidence in themselves even though panic is a natural thing but in the end when we are sure of bitcoin then the decision to rush to sell will never happen.
