Each so often, the system runs an evaluation to see how much time it takes to confirm a brand new block. If it takes computers lower than 10 minutes, the system makes the issue even harder. If it takes more than 10 minutes to verify a block, the system eases off and makes the problem much less complicated. And to high it all off, there is a cap to the number of bitcoins that will ever be produced: 21 million. After the last bitcoin emerges, miners will earn a price for verifying transactions however no new bitcoins can be created.
