Dear friends,
Steemit is similar to other digital currencies. Steemit currency units can be traded, bought, and sold on the open market just like all of the other digital currencies.
With other cryptocurrencies like bitcoin, the actual currency units that are created each day are distributed to the people who run a special bitcoin software program on their computers that perform a process called Bitcoin Mining. The account of computing power you have dictates how much money you get. Every day new Steemit currency units that are created by the network and distributed to the people who engage with the site.
People who created content are rewarded for their content, and people who upvote content are rewarded for helping to curate the best content available on this site. But you don't want to hold on these for too long because more steem Units are created every single day.
So, there is Steem, Power and Dollars.
