I believe that people who are in profit may end up staying if it is a good coin, but when it is a risky one then getting out is more important. Like for example if you invest into bitcoin and not sell when it peaks, that's fine because it may peak again a few years later, like lets say you didn't sell at 68k, you could have bought a lot more if you did, so it is smart to sell at peak but let's assume you didn't, doesn't mean that you are going to lose all your money, you could still end up holding it and sell at the next peak when the bull run happens.
You didn't sell at 68k? Then you can hold for 10 years and sell at 500k, it is still possible and will give you a greater return. But at low stuff like doge, that's not possible.
If you sold not at 68k but at 50k, you would still have an excellent chance of increasing the number of your bitcoins. But the eternal hold strategy may not work all the time, what if something changes after this bull market, what if this is the last bull market?
I’m not saying that this is so, I just want to say that it always makes sense to take profits, this can give you advantages in different situations and maintain your profits. Of course, to successfully carry out these actions, you need to have a good ability to analyze the market, otherwise you can make too many mistakes, due to which you can miss out on big profits.
That is a whole another topic of discussion. That means we need to question if the price will keep going up in the future or not. Like for example, in the next 2 years people assume that the price will go up, maybe you do not think that it will, maybe it won't, maybe the price peaked at 68k, and it will not reach that again, or at least for another 10 years, who knows? In that case, yes you are right, eternal hold forever logic will be a terrible one and you should not be doing that.
I personally disagree with that mindset, I think in the next 2 years the price will go above 68k, and then in another 6 years or so, it will go more than that too, every cycle it happened like that and I do not see a reason why that should change. I am not saying it will, because "will" is a big word, I am saying that's what I believe, as a personal opinion. If I am wrong, I will lose money, if I am right then I will make a profit, totally based on my own moves and not anyone else's.
