A standard GPU rig is made out of a processor, a motherboard, a cooling system, rig frame, and a number (usually 2 – 8) of advanced graphics cards.

Getting a hold of Bitcoin mining hardware can be tricky as there is tons of demand for these machines. The computers that mine Bitcoin are called ASICs or “Application Specific Integrated Circuits”. You can buy them through many online retailers or order them straight from a manufacturer. The profitability of mining Bitcoin depends on several factors, including the price of Bitcoin, the cost of electricity, and the difficulty of mining. When the price of Bitcoin is high, mining can be very profitable. However, when the price of Bitcoin is low, mining may not be profitable.

The difficulty of mining Bitcoin is adjusted every 2016 blocks, or approximately every two weeks. This adjustment is designed to ensure that new blocks are created at a steady rate. The more miners there are on the network, the more difficult it becomes to mine Bitcoin.

The first Bitcoin miner to pass the battery of tests and add the requisite block to the network gets 6.25 BTC as a reward. These rewards are cut in half every time 210,000 blocks are added to the blockchain or every four years. “Proof-of-work is essentially one-CPU-one-vote.” That is how Nakamoto expressed his vision in the 2009 white paper.

Only guesswork which successfully contributes towards the solving of a hash is rewarded. So, if the processing a miner does is deemed not to have contributed towards a solve, a reward is not assigned. For every target hash, there are trillions of possible combinations.
