1,000,000,000 only...why not 100,000,000,000 ? ...was better
...you never know

At a rate of ~100 Resilium per generated token, a total supply of 1,000,000,000 is enough.
We could go 1.000.000.000.000.000 as well, but a token needs some value, and value is set by demand and supply.
Lower limits could trigger demand/supply over the years to come.
