In order to make some sense of the whole ecosystem I started digging up YouTube videos about Steem and the Steemit platform, this is probably one of the best ones I’ve found that makes complete sense:
If you don’t want to watch the whole 12 minutes video here’s a quick breakdown of what’s explained in it:
Steem – Is the basic cryptocurrency used to power this whole system. It’s like the bricks used to build Steem Dollars and Steem power (will be explained in a moment). You can buy and sell Steem, speculate on it’s price or convert it to Steem dollars and Steem power. But if you’re not looking to speculate on the price or if you’re not cashing out your Steemit earnings, you don’t need to deal with Steem directly.
Steem dollars – This is the currency of the Steemit platform and is also known as SMD. This is what people send to one another when they upvote posts on Steemit. The reason it’s called Steem Dollar is because 1 Steem dollar represents any amount of Steem required to reach 1 USD depending on the exchange rate at that time (more or less).
However unlike Steem, you can not use Steem dollars outside of the Steemit platform. You will first have to convert your Steem dollars into Steem and only then you will be able to convert that Steem into Bitcoin or USD.
The reason Steem dollars were created is because the founders wanted to peg the value of Steem in some way to the US dollar, so that people will be able to trade inside Steemit but not be afraid of exchange rate fluctuations. This way if you trade, for example, 100 Steem dollars you know you’re giving away 100 USD worth of Steem.
The Steem dollar is just an IOU, a promise – if and when you decide to cash out of your Steem dollars, you will get however many Steem it takes to get to that value in USD. There’s also an interest acquired on any Steem dollars left in your account (currently 10% a year). This is done in order to incentiivize people to leave their Steem dollars in their account.
Steem power – Also known as SP in short, is basically a token symbolizing how much influence you have inside the Steemit platform. If you have a lot of SP your upvotes will count more and will award different authors SP and Steem dollars as well.
