Not sure
The hard fork caused the first 580800 ixc to be frozen/burned/ lost forever
 there is a fixed production of 1 ixc / block .. till 21,580,800 ixc

 in reality every time someone send some ixc to one of the addresses of the first 6050 blocks (composing the original 580800 ixc), the quantity sent is automatically burned, but the quantity of ixc miners can still mine is increased (the total circulating ixc will never be superior to 21 M) 

I dunno now how many ixc have been donated. I don’t have a downloaded ixc wallet

Technically the process (donation > re-mining)  could continue forever

So without donations, the time left is: quantity left (use command miningfund to check) divided by the daily number of generated blocks (1 block = 1 ixc reward)

Am I clear?
