When the ICO was done the 10% of 2^32 was chosen as the number of MAIDSAFEcoins to create. There is slightly more than 10% of 2^32 MAIDSAFEcoin because of an issue during the ICO
This is not quite the way it works. A coin is destroyed when you purchase resources off the network. And unrelated to that destruction of spent coins there are coins created as rewards to the farmers at the rate set by the farming rate dynamic value.
The point is that the 2 are separate processes,
- coins destroyed when they are spent to buy resources.
- And coins created for farmers.
One day you might have 1000 coins destroyed because of spends to buy resources, but only 250 coins for farming rewards.
And the next it could be 600 destroyed because of spends to buy resources and 900 created for rewards.
The total coins the network could possibly create are 2^32 (around 4.3 billion)
