Welcome Raja;

You can dedicate as much time as you like to STEEMIT. I would suggest that you consistently come on everyday and either produce content or even better when you are just starting out Comment on other peoples Postings so they can get to know you. STEEMIT makes money by people producing content and by steem being mined. I would tell you one of the people you may want to Follow right away would be Hive account@jerrybanfield.
