The reason I am selling is because I am afraid of a bigger loss and after a few days I sell, the price of the asset has increased again.

I understand you buddy, perfectly this exact situation happens to me almost all the time after I sell an asset, the price tends to rise again😅.

If you have joined the market of your choice, determine a strategy

That’s true. Some investors do not actually know their style whether they prefer trading or holding. So they end up buying at a certain price and instead of making profit, they sell and make lose. Thank you for sharing and good luck.
