Northern Washington is were one of the largest US Bitcoin mining is occurring. This location produces 7 Bitcoins per day and only 1800 a day are mined wold wide. Every 4 years there is a havoc cutting the Bitcoin production in half and the next one will be in mid 2020. These machines have only one purpose that is to mine Bitcoin and they unitize ASIC processors (Application Specific integration circuit.) These machines were only created to mine the Bitcoin on the Blockchain and nothing else, but they are very efficient at what they do and they do it well. The miners (aka the computers)solve a very difficult math problem and that pool of miners that solves this puzzle get a share of the Bitcoin, but as more miners come online the puzzles get even more difficult. The final Bitcoin that will be mined will be in 2140.
