Bitcoin and other cryptocurrencies are like the email of the financial world. Everything is done publicly through a transparent, immutable, distributed ledger technology called blockchain. No more bitcoin can be created and units of bitcoin cannot be destroyed. In order to incentivize the distributed network of people verifying bitcoin transactions miners , a fee is attached to each transaction.
The fee is awarded to whichever miner adds the transaction to a new block. Fees work on a first-price auction system, where the higher the fee attached to the transaction, the more likely a miner will process that transaction first. Even changing one character of the input will result in a totally different fixed-length code. This method of requiring miners to use machines and spend time and energy trying to achieve something is known as a proof-of-work system and is designed to deter malicious agents from spamming or disrupting the network.
They also earn any transaction fees attached to the transactions they add to the new block. A new block is discovered roughly once every 10 minutes. Bitcoin block rewards decrease over time. Every , blocks, or about once every four years, the number of bitcoin received from each block reward is halved to gradually reduce the number of bitcoin entering the space over time.
As of , miners receive 6. The next bitcoin halving is expected to occur in and will see bitcoin block rewards drop to 3. As the supply of new bitcoin entering the market gets smaller, it will make buying bitcoin more competitive — assuming demand for bitcoin remains high. The process of requiring network contributors to dedicate time and resources to creating new blocks ensures the network remains secure. But that security comes at a price.
As of , the Bitcoin network consumes about 93 terawatt hours TWh of electricity per year — around the same energy consumed by the 34th-largest country in the world. Not to mention, Bitcoin is a complete financial system whose energy consumption can be measured and tracked, unlike the fiat system, which cannot be accurately measured and requires a range of additional layers to function, including ATMs, card machines, bank branches, security vehicles, storage facilities and huge data centers.
There were also a range of other developers including Pieter Wuille and Peter Todd who contributed to the development of Bitcoin Core — the first client on the Bitcoin network. A client is a piece of software that enables a network participant to run a node and connect to the blockchain. An American nonprofit called the Bitcoin Foundation was founded in to support the development and adoption of the Bitcoin protocol. After three years, however, the foundation eventually ran out of cash and was dissolved.
In , Adam Back, another cypherpunk and the inventor of Hashcash — a cryptographic hashing algorithm created in which used the same proof-of-work mechanism that Bitcoin would later adopt — co-founded Blockstream. Blockstream is a for-profit tech company that develops new infrastructure on the Bitcoin network, including Lightning Network and sidechains.

The use of Bitcoin for treasury management at companies also strengthened its price in MicroStrategy Inc. SQ have both announced commitments to use Bitcoin instead of cash as part of their corporate treasuries. Bitcoin halving events, in which the total supply of Bitcoin available in the market declines due to a reduction in miner rewards because of an algorithmic change, have also catalyzed price increases.
Finally, economic instability is another indicator of price changes for Bitcoin. Since its inception, the cryptocurrency has positioned itself as a supranational hedge against local economic instability and government-controlled fiat currency. Countries like Venezuela, which have experienced hyperinflation of their currencies, have seen huge increases in the use of Bitcoin as a means of transaction as well as storing wealth.
It was traded for free initially between early adopters. Predictions for the future value of Bitcoin vary based on who makes the estimate. Yet others predict that Bitcoin is just a bubble and they are worthless, predicting a very low value in a decade.
