Yes, I used to be like that, bro, I didn't dare to put money in when the market became bloodier and it formed doubts that made us even more afraid to jump in because the price has the potential to fall more, but if you are used to seeing that blood is an opportunity to buy you will get a different mentality from people usually, on the other hand you see the situation as an opportunity and on the other hand you are also doubtful because it is quite terrible with very tense conditions in the market.
Even DCA is a bit scary, but if you really focus on collecting the number of bitcoins I think you will get rid of that stigma within you, and you need to remember that you also have to start trying and getting used to it, if you really don't want DCA's quota to be included in everything at a moment like that, maybe dividing it into several parts is better for you, sir.
That mentality cannot be created by mere thought or impulse, but experience from previous events will make it stronger.
The reason why becoming a good investor or trader is so difficult is that it runs contrary to what we consider common sense, if an asset is rising in price the most natural thing to do is to assume this is going to keep being the case and we will want to become part of that bull movement, however the bull market is the moment to sell not to buy, and the bear market is the same, as many sell at the time when they should be looking to buy instead since the price of bitcoin is very low during that period.
Yes, we still see that it is a habit of short-term traders or investors, and I also don't deny that because such things are like a separate culture in the market.
You will definitely think very unnaturally, or upside down like red is the time to buy and green is for selling, that's a mindset that people rarely do because it's against themselves to make a profit, so what looks green is more attractive and they think that it will continue and red they sell because they are afraid like you said, it's difficult for someone to make a reverse mentality like that in conditions like this, but it also depends on their individual goals and beliefs, those who think long-term don't have to be afraid of a decline, because bitcoin will always return to its best position.
