Welcome to Steemit.
I can tell you that you can indeed earn money by blogging and commenting on Steemit if other people upvote your posts. But Steemit itself cannot generate dollars. You accumulate a cryptocurrency called STEEM. Check the FAQ for more info about how it all works.
Anyway, have fun blogging!
Yes, that is also what i mean but i am wrong in writing it
Give your voice 100% for me sir
