Ok, we have coded in 20,000 but it's nothing for us to modify this later. However we had in mind that 50% of the total supply would be mined, and the other 50% would be earned as interest/nodes, etc. We would have to recalculate the whole block reward to do 80,000 as the block reward is 250 Dogecoin Cash. But, as said there will be many updates once released.
