It is easy to create a stable coin. A detailed project does not imply any technical uniqueness. It seems to me that the most difficult thing in such projects is to guarantee the reliability of this asset and to generate user confidence.
Here the fact of the stability of the coin is important. That is, the team must have enough own funds to support the exchange of coins for altcoins at a fixed rate.
