Hi @crypto.piotr

I'm happy that you have read this post. It is a work in progress inspired in @nnnarvaez thoughts about exploring the economics of Steem and the economic model of steem like blockchains.". The idea is that people provide feedback, explore or test different settings in a steemit clone blockchain.

Regarding stable coins I think they are important to bring mass adoption for daily transactions like selling, buying, taking loans, lending money, and so on. The majority of people are not traders/investors.

For example, freelancers at @steemgigs would prefer to receive payments in a low volatile currency like SBD.

On the other hand STEEM/SBD could have the ability to compete with Maker/DAI or Bitshares/BitUSD, or even USDT or GUSD, although it sounds utopian.

Unfortunately SBD broke its peg to the USD long time ago. But this should be taken as a "hard lesson" to move on. In fact, the community (users and witnesses) should help to maintain the peg:

With a three-and-a-half day window, community members have approximately one-and-a-half days to re-spond to any issues that come up.

The whitepaper also says:

In effect, feed producers are entrusted with the responsibility of setting monetary policy for the purpose of maintaining a stable peg to the USD. Abuse of this power can harm the value of STEEM so SP holders are wise to vote for witnesses who can be counted on to adjust the price feed according to the rules outlined above.

Finally, I don't mind that you share this

have a nice day :)
