"The cool thing about bitcoin that is under-appreciated by a lot of the naysayers is that it's a portable market; you can bring it right to the source of energy," said Steve Barbour, founder of Upstream Data, a Canadian company that manufactures and supplies portable mining solutions for oil and gas facilities. Satoshi Nakamoto designed Bitcoin to be released at a predictable rate, thanks to what is called the block reward mechanism. For every 210,000 blocks, the reward for finding a new block decreases by half. The first set of 210,000 blocks awarded the miner of a block 50 BTC; the next set awarded 25 BTC per block; and the current set of 210,000 blocks will reward miners 3.125 BTC per block. An inflation schedule provides a visual representation of the issuance process. The last bitcoin could be mined sometime around 2130.
