Absolutely!

Over-diversification can be detrimental to your investment portfolio. While diversification is important to reduce risk, over-diversification can lead to:

1. *Additional costs*: The more investments you have, the more transaction and management costs you will have to pay.

2. *Dilution of returns*: Over-diversification can dilute the returns of your most profitable investments.

3. *Complexity*: A highly diversified portfolio can be difficult to manage and monitor.

4. *Loss of focus*: Over-diversification can lead you to lose focus on your investment goals.

In short, you lose less but you also gain less. My advice is to choose 3 to 5 assets, keep track of them, stay informed about all the news related to them, and average your purchase only when it is declining.
