I'm not an expert i bought some maid. Somebody can explain me why on maidsafe.net we have this : Only 4.3 billion coins will ever be in circulation at one time and each will have its own unique identity. Safecoins will be recycled when users exchange them for network services, ensuring there is always a supply for users to earn.
for instance we have this number of coin on CryptoCurrency Market Capitalizations Circulating Supply
452,552,412 MAID *. * Not Mineable
With 4.3 billions coins how it will be capitalized.
Regards,
When you PUT (upload) data to the network you give up some of your Safecoin. That address is now free again and ready to be farmed by someone who delivers data to the network from his Vault. So if 50% of all the coins are mined, 50% of all the Farming Attempts will fail. The group responsible for your Farming Attempt will pick a random address.
