Mining is such a tricky business now, I say that because the more the market cap is filled, the difficult it is to mine coins. And so, as more and more Bitcoins are mined and the market is filled by it. It would be more difficult to mine the remaining ones. Also, like any other currency it's not just the creation, or in Bitcoin's case, mining, that could make it prosper. The transactions and healthy circulation of the assets that are already in the market would play a bigger role in keeping the value of Bitcoin up. Why would you rely more on those assets that are not mined yet, when there is so much more to do business with that is already in the market.
