How can miners make money if there's nothing to mine?
Miners don't make money from Bitcoin buy and sell operations, they ensure Bitcoin transactions "Send and Receive" are confirmed successfully. They solve some certain puzzle to complete a block to allow a transaction to go through, that's what they actually do not on buying and selling Bitcoin.
You would have let him worry about where the fees go. That’s where the gold mine is because as it is, mining hasn’t been much of a profitable venture when it’s about the Bitcoin block rewards. Fees is one way to collect from everybody and it’s the one thing that isn’t going to run out should the last Bitcoin be mind in 2140,,, that’s a long time now. Miners are having to share their mining power anyway, forming clouds and resources together all that. The fees and ensuring the integrity of the network serves real good.
