Why Do Miners Get New Bitcoins?
This adds an incentive for nodes to support the network, and provides a way to initially distribute coins into circulation, since there is no central authority to issue them. The steady addition of a constant of amount of new coins is analogous to gold miners expending resources to add gold to circulation.
In our case, it is CPU time and electricity that is expended. Each time a new block is added to the bitcoin network, freshly minted bitcoins are rewarded to whichever miner discovered the valid block. Sometime next month, this number is expected to fall to According to the Bitcoin Core Client, main. This dictates that every , blocks, the amount of new coin released should suddenly cut in half.
As the code runs, it continues to calculate how many blocks have been solved. When the number hits ,, the first halving event takes place. This means that once there have been 64 halvings, there should be no further nSubsidy released. In other words, after 50 has been divided 64 times, the last bitcoin will have been released into the market and the total 21 million supply will be in circulation. Unlike with other perceived deflationary assets, it is crystal clear in the code that there will be a maximum number of bitcoin — and it is through this halving process that this state of affairs is achieved.
Miners, as one can imagine, stand to be impacted the most when the next halving event takes place. In the white paper, Satoshi explains that the addition of bitcoin comes at the expense of CPU time and electricity. At least one miner has moved to pull the plug ahead of the halving. Unlike with gold or another precious metal where a new, big discovery can happen at any time, miners know exactly what to expect and when. For example, if miners were selling all 25 of their bitcoins per block to pay their bills, this would be an introduction of 25 new bitcoin into the market roughly every ten minutes though this can fluctuate depending on network variance.
Therefore, just because a miner sees its subsidy drop from 25 bitcoin to By February , however, the hashrate had returned to its previous high and continued to rise from there. Miners had lost half of their bitcoin subsidy, but the price had increased enough to more than offset this.
Today, the network hashrate stands at 1. For context, that is 1. Over the next few days, the hashrate dropped from 1. I talked to some Chineses miners at Scaling Bitcoin and learned something interesting. Most miners have found electricity for free or close to 0 cost. In other words, while profit did drop, it was all profit at electricity rates.
With a significant percentage of mining taking place in locations that already provide cheap electricity, the outcome could be similar when the number of new bitcoins introduced falls: the hashrate may drop, but it might not be as significant a drop as it was the first time.
The exact impact on the network — and the price — remains to be seen, and the weeks leading up to the event will likely see no shortage of commentary and speculation as to the outcome.
