If you know what you're doing very you will have a time limit of when to leave and when to stay longer, not all early exit or late exit gives advantage, it depends on your strategies and your target.
Exactly, it's all about being aware of what you are doing, which means that if you are into trading, you should know when you had bought a certain coin, I mean at what price, and then you should be able to sell it at a price that you initially had in mind, one should rather place a sell order exactly after buying a coin so that they don't forget later, which they shouldn't. When it comes to investments, like when you invest money in Bitcoin, you should always have a target for taking profit, and then you shouldn't exit before that price, when you do, and the market goes higher, don't regret doing that, because it could come down as well.
A lot of people regret why they sold early when they see the market going higher than their initial target, but selling and making an exit earlier when your target has been hit is better than holding longer and then seeing the market going down right after hitting your target, and believe me, it happens a lot in a volatile market like this one. So no one should regret making an early exit as long as they know what they are doing and their strategy makes them do this.
