First of all, incremental buying; it is done by dividing the balance you allocate for investing in an asset into several parts to reduce costs against negative price movements that may occur, and it is extremely important, especially for medium to long-term investments. Now let me explain with an example.

For example, I researched the project of X Coin, liked its roadmap, team, and tokenomics, and decided to allocate $1000 from my portfolio to this coin.

If I allocate this balance directly to X Coin at the current price, it would make me unprepared against future price movements, so I should prefer to make a purchase with at most 20% of the allocated balance initially.

After that, depending on the significant price movements that will occur, I can reduce my costs with purchases and sales at important price levels in case of a drop, or in case of a rise, I can increase my cash with gradual sales and, when it comes to my cost, I can increase the number of coins with a new entry.

"I bought and it dropped, I sold and it skyrocketed" - do not neglect to make incremental purchases and sales to avoid saying this :) I hope I have explained the topic well.
