Personally, I also sold some bitcoin when it hit $69k and I was happy with the profits I got. Although I also expect or hope that history will repeat itself, that we will have a bull season after the halving, but it is never wrong to take profits because the future is unpredictable. There is no guarantee that we will have a bull season after the halving.
Yes, you may be right, profit taking is never wrong. However, what is important is what we do after taking profit. I'm wondering what your next plan is after you sell some BTC at 69k USD? Continue to wait for price movements after halving to buy back BTC or will you not buy back the sold Bitcoin anymore?
If you continue to stay in this market, and after the halving event the price of Bitcoin increases above 69k USD, you may have to buy it back at a higher price. And so, I think that selling at 69k is not a profit-taking action, but a tendency to trade more (selling at a high price and waiting for a lower price to buy optimal quantity).
If you do not buy back BTC and are satisfied with the profit you have achieved, then that is exactly profit taking. Congratulation.
