When you get a perfect entering you won't be concerned about getting the perfect exits because every exits that you sell after your purchase, you'll still be making profits that's why entering are always more important. For someone that bought Bitcoin at $10k any price that he sells above that price that he bought the Bitcoin is going to be a win for him. What I think is that we shouldn't be worried about what the entering price is now but should buy when we have the chance to buy Bitcoin through DCA so that we can have better opportunities to buy more Bitcoin for lesser amounts. We should also try to avoid having regrets of not buying enough Bitcoin when the opportunity was there hence we should always make sure we buy with enough amount.
It's very easy to look at previous prices of Bitcoin and say that ideal time to buy bitcoin was when it went under 20k$ towards the end of year 2022 and hodl it till price touched 109k$ in that start of 2025. In real life we are not sure when price is going down what's the bottom or when price is going up what's the top. The best way to sail with Bitcoin is to accumulate them over a period of time using DCA technique. If you follow DCA technique it frees you from worries of when to enter and exit, provided you are following it for 5 years or more.
