The probability of calculating a hash that starts with many zeros is very low, therefore many attempts must be made. In order to generate a new hash each round, a nonce is incremented. See Proof of work for more information.
The Bitcoin Network Difficulty Metric The Bitcoin mining network difficulty is the measure of how difficult it is to find a new block compared to the easiest it can ever be.
It is recalculated every blocks to a value such that the previous blocks would have been generated in exactly two weeks had everyone been mining at this difficulty. This will yield, on average, one block every ten minutes. As more miners join, the rate of block creation will go up. As the rate of block generation goes up, the difficulty rises to compensate which will push the rate of block creation back down.
Any blocks released by malicious miners that do not meet the required difficulty target will simply be rejected by everyone on the network and thus will be worthless.

The Block Reward When a block is discovered, the discoverer may award themselves a certain number of bitcoins, which is agreed-upon by everyone in the network. Currently this bounty is 25 bitcoins; this value will halve everyblocks. See Controlled Currency Supply. Distributed hash power spread among many different miners keeps Bitcoin secure and safe. Chapter 3 How to Mine Bitcoins Actually want to try mining bitcoins? Well, you can do it. However, it’s not profitable for most people as mining is a highly specialized industry.
Most Bitcoin mining is done in large warehouses where there is cheap electricity. Most people should NOT mine bitcoins today. Most Bitcoin mining is specialized and the warehouses look something like this: ASIC miners are specialized computers that were built for the sole purpose of mining bitcoins. You will earn less than one penny per year and will waste money on electricity.
Select a Mining Pool Once you get your mining hardware, you need to select a mining pool. Without a mining pool, you would only receive a mining payout if you found a block on your own.
This is called solo mining.
