In this part of the guide, you will learn how to pledge to your stakepool. Pledging means delegating from the stakepool address tADA to the stakepool. It's used to see if the operators are trustworthy, because the more money you delegate to your own stakepool, the more confident you have to be in the profitability and success of your pool. Besides, it's also used to limit the amount of pools someone can create, because you should have the biggest amount of tADA pledged as possible, and this is not possible if you have 20 stakepools for example.
