What is Delegation?
Delegation is a process of delegate some of your Steem Power (SP) to the services @Minnowbooster and 
I delegated 20 SP of mine to @Minnowbooster Bot. I know this is not enough SP to delegate because right now I don't have much SP in my wallet. I performed this task just for the sake of learning that how to delegate & un-delegate SP to/from Minnowbooster Service. You can clearly see my (-20.578 Sp) delegation underneath my SP which is shown with a negative sign, It means I can't use that amount of SP for a certain period to Upvote anyone with my full SP.
Note: You've to keep in mind that If you delegate some of your SP to any services, you are not losing your SP and your SP is fully safe because you can undelegated your SP at any time. The best part is that it is the most risk free way of earning some passive income.
How to Delegate SP to Minnowbooster (MB)?

How to Undelegate SP from Minnowbooster (MB)?
A lot of people delegate SP to Minnowbooster to earn some passive income, but later on, when they want to undelegate their SP back from this Service, They didn't find any option to undelegate their SP back. So I thought I had to explain the way to undelegate your SP back from Minnowbooster by following some simple steps. As I said before that I delegated my SP to MB just for the sake of learning because I know I couldn't earn enough passive income from my 20 SP delegation. So let's get started.
The undelegation process is quite similar to the delegation, means you have to select the Delegate to Bot option from the MB website and fill out the fields, but this time you should write a negative sign beside the number of SP that you want to undelegate and then click the Delegate CTA to move forward. If you still find it difficult, So basically take a look at the image above.
Once you clicked on the Delegate CTA, You will move on to the next page where it shows like the image below with the Steem Power of 0.000 SP. then press continues and follows the similar steps as you did while delegation and the Steemconnect basically understand that you want to undelegate your SP.
After completed all the process, You will successfully undelegate your SP from Minnowbooster Bot, but It takes 7 days to get your SP back in use after undelegation. As always you will get a message on the https://steemd.com/ website like the image below.
Now I'd like to hear from you about delegation and any other way to undelegate SP from MB by sharing your useful thoughts in the comment below.
