Steem proposes a complex economic system where the aim is to reward users who bring good original content to the platform. For that, it uses an economic instrument called currency inflation. That is, it creates money out of nothing, prints bills like the big banks do for themselves, with the difference that in steem that money is used (among other things) to reward those who truly do the work.
That currency can be used to buy steem power (SP), which gives the user benefits proportionally to the amount of SP. There are several accounts with huge amounts of SP called whales, whose benefits are reflected in the capabilities they have. Mainly the SP they have, ponderates their voting power. That is, they can affect the fate of a post more than other users with a single vote. Some become so powerful that they are called demigods!

If you are interested in knowing a new platform to expose and monetize your work, I recommend you follow me on steem. I am working on a project that will solve these problems and I will be releasing information about it soon.
