Your right, I was just trying to show in terms to understand that even when a block solved only gives you 12 or 6 BTC the fee's will easily make up the difference imo.
Agreed. I don't think the OP understood mining. I think he actually thought that when bitcoins reach the maximum number, mining is done. he did not realize that it will always be used to secure the blockchain, and in the future, mining will be paid on fees.
