Bitcoin Miners Made $14 Billion to Date Securing the Network

All-time revenue for Bitcoin (BTC) miners has topped $14 billion, according to fresh data from Coin Metrics.

As Yahoo! Finance reported on Aug. 30, despite the massive increase in the network’s hash rate — a factor that depresses the profitability of mining — there’s still more money in the game for miners than ever before. 

Introduction To Bitcoins

Bitcoins are a digital currency created in 2001 by Satoshi Nakamoto. It is based on open source software and P2P networks with no central authority or issuers. The coins are saved on your computer in a wallet file or in a third party wallet. They can be exchanged between anyone with a Bitcoins address. The database of transactions is spread across a peer to peer network. They also use digital signatures to ensure they are only spent once and by the person who owns them.

They are created by a process known as Bitcoin mining. There is where you use CPU power on your computer in order to generate them. This also generates the encryption keys which keep bit coins secure. By generating the encryption you are rewarded with Bitcoins for your effort.

While the transactions are public the transactions themselves are psudeononymous. Many people who are concerned about privacy like to use Bitcoins for this reason.

They are bought and sold through exchange sites. There they can be exchanged into traditional currencies like the Dollar or Euro or for virtual world currencies like the Linden dollar.

Bitcoins have no central control so they cannot be controlled by any government or authority. There are also no chargebacks.

There is a limit to how many can be created. There can be 21 million Bitcoins in total. This is to avoid the currency from becoming worthless from overproduction like fiat money. Diminishing geometric expansion combined with the expansion of Bitcoins provides an incentive for early adopters.

There are some scenarios of for failure that could happen to Bitcoins. These include a currency devaluation, a declining user base and a global government crackdown on the software and exchanges.

In order to get started to generate and trade Bitcoins you have to download and install what is called a Bitcoin client to your computer. This will give you the Bitcoin wallet and address. When people want to pay you give them your Bitcoin address and they send it to there.

If you want to make Bitcoins you are going to have to mine them. You do that by giving up your processing power to the Bitcoin network so it can encrypt transactions. You can create one block every ten minutes. Every block is 50 Bitcoins. You can use your computer to generate them when you are not using it or create mining rigs dedicated for that purpose.

Bitcoin miner revenue growing exponentially

The report notes that as of the Bitcoin network’s inception, it took eight years for miners’ total revenue to break past the $5 billion mark; the next $5 billion were exponentially faster, taking only a further eight months for revenue to break $10 billion.

If current mining profitability remains on track, the $20 billion revenue mark will be broken sometime in early 2020.

Solid revenue despite soaring hash rate

The $14 billion figure is all the more impressive given that the network’s hash rate has been on a tear for several months now: continuing to break previous records throughout summer— with a new all-time-high posted just today, at 83.5 TH/s by press time.

A higher hash rate indicates that miners are expending record levels of computational processing power to solve and validate blocks — and pocket their rewards.

Higher compute intensivity translates into higher operational costs for miners — yet the robust revenue increase indicates this factor has not critically dented profitability. 

Looking ahead, Bitcoin is under a year away from its next halving — a pre-coded 50% reduction of block rewards for miners — which is slated for May 2020. 

While the halving can have bullish implications for a cryptocurrency’s price (by increasing scarcity), its impact on miners is keenly watched, with some concerned that lower block rewards will deter network participants and thus adversely impact the network’s hashing power.
