Miners race each other to complete the work, which is to “package” the current block so that it’s acceptable to the rest of the network. Acceptable blocks include a solution to a Proof of Work computational problem, known as ahash . The more computing power a miner controls, the higher their hashrate and the greater their odds of solving the current block.
More importantly, it allows you to put your miner to work and start making money by connecting to a pool, or to the Bitcoin network if you are mining solo (not recommended).

A high concentration of mining activity in one country threatens the entire system that underpins cryptocurrencies. Vulnerabilities arise when so much mining capacity is concentrated in one place. One of the core security pillars of the blockchain technology upon which cryptocurrencies operate is that transactions are transparent and publicly verifiable. This means that if one actor within the system corrupts a ledger “block,” every peer can see the inconsistency, flag it and correct the mistake on their own corresponding records, maintaining order without the need for a central authority.
Bitcoin mining is a booming industry, but the Bitcoin price increasing can help make up some of these losses.
In most cases, though, there is no mining facility or hardware. There is just a guy taking your money and paying part of it to someone who signed up before you did. Eventually he runs away with the money, and you are left with nothing.
The Antminer S5 may not be the latest Bitcoin mining hardware (other models like the S7 and S9, have come after it), but it is still in use, and its efficiency and function is exemplary.

One interesting cryptocurrency that requires little effort to mine and is accessible with low-cost computing power is FoldingCoin (FLDC). Instead of mining by crunching arbitrary calculations, as with bitcoin, FoldingCoin uses your home computer to run protein fold simulations to help scientists fight diseases such as Alzheimer's and Parkinson's disease. The FoldingCoin price is currently hovering around $0.001 and set-up information is available on its homepage.
The second source of revenue for Bitcoin miners is the transaction fees that Bitcoiners have to pay when they transfer BTC to one another.
So far, Ameren has mined about 20 “coins” and it produces a new one about every 15 days.
Cryptocurrency mining varies depending on the hardware you use and the type of coin you mine. For example, Bitcoin miners need an average of 10 mins to validate and record one block to the network, and for every second, the mining hardware consumes gigawatts (GW) of power. In comparison, the same process takes Ravencoin miners one minute.
Hashing24 has been operating since 2012 and is considered to be one of the oldest services. Since its introduction, no one has ever reported any malpractices being performed during the bitcoin mining process.
F2Pool’s payout method is called PPS+. PPS+ pools take the risk away from miners, as they pay out block rewards and transaction fees to miners regardless of whether the pool itself successfully mines each block. Typically, PPS+ pools pay the miners at the end of each day.

Divided by the average number of bitcoin transactions, that means just two transactions create as much waste as a disposed iPad, said Alex de Vries, a cryptocurrency economist and the study's lead author, reports Quartz.
Despite the profit potential of mining Bitcoin, your Bitcoin mining hardware’s upfront and energy costs can actually do harm to your bank account.
