Both of them serve a different purpose from the other. Trading is to create liquidity when the market is stable. During the past week, the price of Bitcoin was either stable or low, while BTC/ETH was high. If you converted BTC to ETH a week ago and then sold ETH to buy BTC, you will find that what you have of BTC has increased in one week.
Hodling is appropriate when the value of Bitcoin increases, as you will achieve profits without doing anything. Therefore, during 2025, Hodling is much better than trading, but in 2026, trading is much better than Hodling, and so on.

If you are a beginner or don't know what to do, Hodling using DCA is the best.
