Each currency fluctuates based on the economics of that region/country however those fluctuations for each compared to other are not liner. In that case how your Crypto will be valued. For example if USD is going up versus EURO is going down, will this currency go up or down?
Also what problem are you trying to solve by this project? It may also beneficial to state your capabilities (like if you are Developer or Marketer etc.) and what you are looking in your partner to get more interest from people.
My 2 coins...
My idea was not to create a "global currency". As you can already see there are currencies like Tether or TrueUSD which are backed by the USD. But as for example if a person wants to use a StableCoin in Europe then he/she only has the choice to use mainly StableCoins which are only backed by USD. Therefore I just want to create a project which will not only have a Stablecoin backed by USD but also for EUR, RUB or other Fiat Currencies. So Europe for example will be able to use StableCoins for EUR or Russia can have a Stablecoin for RUB.
Creating a Stablecoin is easy but currently I think it for this project we need a Developer, a Marketer and a Lawyer.
