The ecosystem size is the sum of the trade, remittance, investments and reserves with different coefficients, needed to support the turnover of the goods and services in the community.
Today it's about 1B XDR needed for the community.
The more people, companies and countries we involve, the bigger the ecosystem size will be.
The bigger the ecosystem size, the more XDRs should be issued to run the economy.
All XDRs are issued via the emission centres.
When the ecosystem will grow to 10B XDR, the emission centres will issue those XDRs.
If one start working as an emission centre at the 1B ecosystem size,
he will issue 10 times more XDRs while the community will grow.
