Limits coinbase to 21M (thx genjix)
It would indeed be best to be closer to Bitcoin's 21M limit. So I've updated the nHeight to 227499. We still get a decrease to a 48 reward in the last 17499 blocks. This will be a warning sign to miners that they'll soon have to rely exclusively on transactions fees ~3 months later.
Thanks for your input kr105rlz and best of luck with i0coin.
