Hello everyone, I would like to know about staking, I roughly understand what it is, but is there any point in staking in BNB, let's say for $10,000?

Is it possible for BNB to drop while staking?

If I did this and earned some coins, is it better to sell them right away or wait for the price to rise?

Thank you all in advance for your answers.

Wishing everyone a good day and good growth.
