What I learned about Steem so far

Hello friend Steemers,

this week I came across Steem and I instantly got sucked into it! In this post am trying to summarize what I learned about it so far. Please feel free to correct me if I got something wrong, I am still learning about this extremely interesting platform.

To understand Steem, first of all we need to understand its currencies. According to the whitepaper we have:

Steem - the fundamental unit of account on the Steem blockchain. All other tokens derive their value from the value of STEEM. Generally speaking STEEM should be held for short periods of time when liquidity is needed. Someone looking to enter or exit the Steem platform will have to buy or sell STEEM. Once STEEM has been purchased it should be converted into Steem Power (SP) or Steem Dollar (SMD) to mitigate the impact of dilution over the long-term (100% inflation annually).

Steem Power (SP) - Steem can be instantly converted to Steem Power. It is a long-term investment and can only be converted back to Steem via 104 weekly payments over a period of 2 years. This long-term commitment gives the owner two advantages:

the user can participate on the platform by voting or posting articles/comments. This is rewarded by more Steem Power (SP) and Steem Dollars (SMD). How much everyone gets, depends on his Steem Power and the voting algorithm.
The inflation is not 100% anymore like with Steem, but only ~10% per year because for every 1 Steem generated as reward, 9 new Steem are distributed among Steem Power holders. If the platform grows faster than the inflation, investors make a win, otherwise they'll be losing money.

Steem Dollar (SMD) - represents a number of Steem tokens having a value of ~1 USD. It can be used to trade goods/services with the stability of the USD. SMD pays holders interest (currently 10% per year). The interest rate is set by the same people who publish the price feed so that it can adapt to changing market conditions.

The two main reward mechanisms in Steem are curation and author rewards. Both are equally important in Steem.

Author Rewards are gained by posting articles that are upvoted by others. Curation Awards are gained by early upvoting articles that grow popular later. The rewards are payed out in Steem Power and Steem Dollars. In general the more Steem Power someone holds, the more weight his vote has. If one of developers is upvoting a post, it can instantly bring more than $100 value to the post. A new account on the other side with ~3 Steem Power will only bring a fraction of a cent. The final value of a post is distributed among the author and curators depending on how early they participated in the voting process and how much Steem Power their accounts hold.

The money for the reward pool is coming from the inflation. Instead of taking a tax on existing accounts for generating the reward pools, the protocol generates continuously new Steem where 1 is going to the reward pool and 9 are redistributed to Steem Power holders. This basically results in a ~10% inflation annually.

Lot of people are asking the question if this model is sustainable, e.g. The Great Steemit Debate: Tone Vays vs. Jeff Berwick "Ponzi Scheme or Paradigm Shift?". One could expect that the model can only be profitable as long as more investors are jumping in. At the moment where supply gets greater than demand the whole system could break together like a Ponzi-Schema. This could be very painful for late-adoptors because of the 2 year payout mechanism.

My personal impression so far is that this could be the first DLT application with good user experience and the potential to go viral. It reminds me a little bit on 2007 and the gold rush with the AppStore. Anyway, I'll stay here for a while and also add some Steem Power. Power on Wayne!
