Take profits or liquidate positions during a bull market. I didn't do this in 2017/2018 bull market and I repeated the same mistake during 2021/2022 bull market. I am promising myself to take profits in the next bull market, let's hope I will know when it is the most opportune to do so.
6-12 months after halving. I need to remember that :)
Right, the next one is in 2024 I think.
