This steemit pretty simple , lets say we doing cloud mining , if you post contents some people will upvote your post , if whales upvote your post then your mining power increasing bigger .the more people upvote your post the bigger amount of rewards you get , just like 12 hours mining power . i hope this comment will make you little clear.
But better get whale to upvote your post.
This is block chain thingy everythjng must connect to each other i think .
