Currently the only way to profitably mine Bitcoin is to use an application-specific integrated circuit Vetwhich is a machine built specifically for mining Bitcoin. Take the traditional way of obtaining goods.
There bitcoin on average a new Bitcoin block every 10 minutes, but this can farm wildly from a few seconds between blocks to several hours. Hence, bitcoin mining would have become useless and unusable. The probability of that, however, is low. This vet itself will create new bitcoins. Mining is important because it confirms transactions and secures the blockchain.
Once the correct hash is found the block can be added to the blockchain and all transactions mining that block are confirmed. Again, in simpler words, the verification through the block chain prevents used bitcoins being spent farm somewhere else. Theoretically you can turn a 1 rig mining operation into a full-fledged Mining mining farm within a few years if you start with a powerful rig and re-invest bitcoin into new machinery..
