As sug-.Dec 15, 2014 Bitcoin has miners because people want bitcoins, but something here seems silly: how did a bunch of bitcoins, the tokens of a man made invention, end Bitcoin relies on miners to record and validate transactions because of a particular problem inherent in any system of digital currency: double spending. receive bitcoin cash Aug 31, 2016 You may ask yourself “where do Bitcoins come from ?” Bitcoins aren't Just like real world mining, you need to invest energy in order to extract these Bitcoins. The miner's computer needs to solve complex mathematical problems, and once it solves them – new Bitcoins are generated and awarded to him. how to make more bitcoins Miners are not so much solving a math problem as they are spending a lot of effort making guesses until they guess correctly. Bitcoin works by having a linked set of "blocks" of transaction records that document who has what bitcoin. Miners are solving hashes of the next block. In bitcoin the algorithm used is SHA256.Bitcoin needs to provide an incentive for people to solve these number crunching problems and it does this by rewarding people with new Bitcoins when they solve a problem. This is the only way that new Bitcoins are created. Doing the number crunching which verifies a blockchain is called 'mining' Bitcoins. The computing  bitcoin scams list 16 hours ago He said the company did not know how the 523 million tokens went missing and insisted the firm was working round the clock to ensure the safety of all client assets.
