Greetings my dear friend!

Firstly let me say your presentation style is very cool. Now let's talk about the contest. You have cleared knowledge about Cryptocurrency mining. But one thing is that Steem is the native currency of decentralized blockchain it can't be mined like other digital currency such as Bitcoin. It can be achieved only DoPS. Stake holders are responsible for this. There are 21 witnesses who are able to produce blocks. They produces blocks after every 3 seconds. In this way there may be 29 blocks are produced within a minute. You have clearly highlight the significance of this. And you have highlighted the multiple benefits and different methods for mining. Yes role of miners is appreciated. Without miners there is no mining. Unfortunately it's banned in our country Pakistani. There are legal Restrictions. Overall I enjoyed your post. Good luck my dear friend.
