Bitcoin exists only online and is tracked through digital accounts, not physical bills or coins. Unlike regular money, there is no central bank in control. Bitcoin uses a blockchain, a shared digital ledger maintained by people around the world. As a result, banks and governments do not control what happens to Bitcoin.
Fundamental Concepts of Bitcoin
- Bitcoin is made up entirely of data and exists only as code within a large digital network.
- No single bank or company controls Bitcoin.
- Instead, thousands of computers around the world work together to keep the system running.
- There will only ever be 21 million bitcoins, which makes them rare.
- Because of this, people often compare Bitcoin to digital gold.
- Currently, one bitcoin is worth about $80,000.
Mechanics of Bitcoin TransactionsHere are the basic steps in a Bitcoin transaction:
- Bitcoins are kept in digital wallets. These wallets protect the secret codes that prove you own your bitcoins.
- Network computers, called nodes, check the following:
- You actually own the coins.
- You haven’t already spent the coins.
- Your digital signature is legitimate.
Miners are powerful computers that collect pending transactions into groups called blocks. They then compete to solve difficult math problems. The first miner to solve the problem adds a new block to the blockchain. As a reward, they receive new bitcoins and transaction fees. block links to the previous one using cryptographic codes, creating a chain of records nearly impossible to alter. The blockchain is a public ledger, open for anyone to inspect and see who owns what.
- The Bitcoin project began in 2008 and was created by someone or a group using the name Satoshi Nakamoto.
- Nakamoto started Bitcoin as a response to the 2008 financial crisis and concerns about money controlled by central authorities.
- At first, Bitcoin was worth only a few dollars.
- As more people became interested and demand grew, its price rose.
- Today, Bitcoin is surrounded by regulations, custodial services, ETFs, futures, payment processors, and many exchanges.
- Early worries about anonymity and crime were partly true, but these concerns are now mostly overstated or outdated.
Verified Facts:
- As recently as 2018, academic studies found that much of early Bitcoin activity was linked to illegal markets, such as drug sales on the dark web.
- Bitcoin transactions do not require the use of real names, which can facilitate their use in illicit activities.
What is often misunderstood:
- Every Bitcoin transaction is recorded forever on the blockchain and can be traced using forensic analysis.
- These records cannot be changed and are open to the public.
- Recent studies show that as Bitcoin has become more common and criminals have moved to privacy coins, only a small percentage of Bitcoin activity is now illegal.
- Since Bitcoin can be traced, law enforcement has seized billions of dollars in Bitcoin.
- This would be much harder to do with cash.
Bitcoin is not a hidden source of untraceable money. Instead, it works more like cash, but with a permanent public record of every transaction. With enough analysis, people’s identities can often be found. If you are thinking about a diverse investment portfolio, here are the main reasons for and against investing in Bitcoin.
Potential BenefitsDiversification and Asymmetric Return Potential
- Early adopters who believed in Bitcoin have seen their fortunes grow dramatically as its price soared.
- Usually, Bitcoin’s price moves independently from traditional assets.
- However, during times of market trouble, their prices can start to move together.
-
Scarcity and Programmability
Because Bitcoin has a limited supply and a fixed issuance rate, many people see it as protection against currency devaluation.
- Bitcoin allows people to send any amount of money instantly to anyone in the world, without using banks or wire services.
- This speed and flexibility appeal to both wealthy individuals and large institutions.
- Today, investors can buy Bitcoin through regulated futures contracts, exchange-traded funds (ETFs), and secure custodial services.
