Just read the whitepaper of steem u will understand. There is a small inflation on steem so every minute, hour or day steem creates new coins. Just excatly the same with every minable coin but now the platform gets percentage of it. Thats about it. Steem just creates more coins which are given to the makers of great content. So lets create great content!
Hope this helps everyone out
