Bitcoin is one of the most widely used types of cryptocurrency. Virtual “coins” or “tokens” are used in a cryptocurrency system instead of physical cash. Coins have no intrinsic value, and they aren’t backed up by gold or silver.
Bitcoin was created to solve a couple of big cryptocurrency flaws. First, it was designed to prevent crypto coins from being fraudulently duplicated. Think about how easy it is to make copies of your computer’s data—documents, photos, files, etc. Cryptocurrency wouldn’t be possible if anybody could duplicate a coin and create an unlimited amount of currency for oneself. You can’t just make copies of a $20 bill, right? Likewise, there’s a need to prevent people from reproducing crypto coins.
How Does Bitcoin Work?
Bitcoin uses a digital technology called “blockchain,” an advanced coding mechanism that disperses a single code over thousands of different computers. For example, let’s say that your coin is built from the code “XDA146DDS.” Blockchain segments the code into smaller pieces and stores the pieces of code across many computers. If a hacker wanted to access the code, they’d have to hack various computers to access the entire code.
Blockchain also employs a “public ledger,” which uses thousands of computers (referred to as “nodes”) to keep track of coins and their owners. If a coin’s data is changed, the nodes will cross-reference their records to verify whether the change is accurate and that the coin’s owner initiated it.
Any time money goes from one Bitcoin wallet to another, it’s logged. Bitcoin wallets store a private key or seed, which is encrypted. This data is used to sign transactions, proving their origin mathematically. The signature also prevents anyone from changing the transaction once it is given. All transactions are broadcast to the network, and within 10–20 minutes, “mining” begins to confirm them.
According to Bitcoin.org, mining assures a chronological chain, network neutrality, and allows several computers to agree on the system state. To be confirmed, transactions must be encapsulated in a cryptographic block.
Changing previous blocks invalidates all succeeding blocks, hence earlier blocks cannot be changed. Mining also creates a competitive lottery, prohibiting anybody from adding new blocks to the network sequentially. As a result, no group or individual controls the blockchain.

What is Bitcoin used for?
Once you purchase coins, you can use them in online transactions wherever they’re accepted. Remember, when you make a transaction with a coin, there’s no actual money being pulled from your bank account. Money only leaves your bank account when you purchase the coin itself—not when you make purchases with a coin.
Like cash currency, the value of a coin may fluctuate. That’s why some investors are getting excited about Bitcoin and other types of cryptocurrency. Investors speculate that Bitcoin’s value may rise significantly if there’s a surge in the market. I’ll explain the arguments for and against cryptocurrency investment later on.
For now, investors should pay special consideration to the rate by which Bitcoin and other relevant cryptocurrencies are being adopted. Not unlike traditional equities, Bitcoin increases in value when more people are interested, and more people are interested in buying Bitcoin today than ever before. Whether it is pure conviction or an inherent fear of missing out on what many predict to be the greatest transfer of wealth in American history, trading volume continues to increase exponentially. For the better part of a year, in fact, Bitcoin trading volume has steadily increased. As a result, Bitcoin is regularly testing new highs.
