However, selling your hiding too early is not good and that is not the main part you are supposed to be talking about. What you should be asking for is how to know the appropriate time to sell.
Although both questions might be similar, they are still very very different, it is easy for you to decide when to sell and when to hold. But the hardest thing is how you will know the right time to sell. It's a bit hard. You can't buy easily but you can sell easily, so selling early is not the best idea to be thinking about, because surely a day will come when you will definitely,, sell your coins. That's why I said the best question for you to ask is the best time you should sell off your holdings.
An investor might decide to sell when he/she has agreed to, from his or her mind, but what happens next when, after selling, the price increases ×10 of what you sold?
It's not possible for anyone to perfectly time the market unless they are extremely lucky or their predictions turn out to be perfectly true. And we are humans, there will either be regret or gratefulness after we are done with selling something that either gains more value or loses value later on. So we can't always keep ourselves safe from both of these feelings. Even if you reach your profit target and sell your assets, you will still regret doing that if you see the asset gaining a lot of value after it.
There are two things a person can do. The first thing is that they keep selling the assets in portions so that they always have some left to be sold when the price goes higher. Or, one can wait until the market starts declining and they should sell their assets at that point, but this can go wrong sometimes because there can be healthy corrections and the market can always go up again after that.
