How are the spreads defined in Green Change?

The website from which we obtain our API rates is an international platform, and our mid-rates align with those found on similar websites.

However, we have the flexibility to determine a spread for ourselves. This decision is influenced by the fact that we receive Rial and need to convert it to Dollars and then Tether. As a result, our rates cannot be directly compared to websites that do not accept Rial.
