Along with impressive gains, BTC has also experienced devastating declines. Bitcoin remains a highly volatile asset, and simple things like an ill-timed tweet from Elon Musk can decimate its value. If you want to buy Bitcoin, experts recommend that you invest no more than a small percentage of your net worth in the leading cryptocurrency. Be sure to check out our top picks for best crypto exchanges , like Coinbase , Gemini and Binance.
You may also choose to buy your crypto on a platform like Robinhood, Paypal or Venmo, though buying crypto this way often means you cannot withdraw your coins and move them to another platform. After choosing an exchange, you have to fund your account before you can begin investing in Bitcoin.
Depending on the exchange, you can fund your account through bank transfers from a checking or savings account, PayPal, wire transfers, a cryptocurrency wallet or even a credit or debit card. Keep in mind, though, that platforms may charge higher transaction fees for certain funding options. Credit card transaction fees on other platforms often run at least this high. Because fees reduce how much money you can invest and therefore also how much money you have to grow and compound , it tends to make sense to use electronic transfers from a bank account rather than other methods.
In addition, if you use a credit card to buy cryptocurrency, it generally will count as a cash advance and be subject to a higher interest rate than you pay on regular charges. Once your account is funded, you can place your first order to buy Bitcoin. When the transaction is complete, you will own a portion of a Bitcoin.
The crypto exchange you use probably has an integrated Bitcoin wallet or at least a preferred partner where you can safely hold your Bitcoin. Some people, however, do not feel comfortable leaving their crypto connected to the internet, where it may be more easily stolen by hackers. If you want ultimate security, you can store your Bitcoin in an online or offline Bitcoin wallet of your own choosing.
But keep in mind that if you move crypto off of an exchange, you may have to pay a small withdrawal fee. In addition, if you use a third-party crypto wallet custodian, you may also be permanently unable to access your coins if you lose the private key that serves as your wallet password.
This has locked some Bitcoin millionaires out of their fortunes. Most exchanges offer multiple order types, so you can decide to sell only when Bitcoin reaches a certain price, or you can place an order that goes through immediately. You can choose to sell your entire holdings of Bitcoin or only a specified amount. Once the sale goes through, you can transfer the money to your bank account. Your exchange, however, may have a holding period before you can make a transfer back to your bank account.

How to Buy Bitcoin in 4 Steps 1. Featured Partner Offers. Learn More Via eToro's Website. Bitcoin was created as a way for people to send money over the internet. The digital currency was intended to provide an alternative payment system that would operate free of central control but otherwise be used just like traditional currencies. Cracking this is, for all intents and purposes, impossible as there are more possible private keys that would have to be tested 22 56 than there are atoms in the universe estimated to be somewhere between 10 78 to 10 There have been several high profile cases of bitcoin exchanges being hacked and funds being stolen, but these services invariably stored the digital currency on behalf of customers.
What was hacked in these cases was the website and not the bitcoin network. In theory if an attacker could control more than half of all the bitcoin nodes in existence then they could create a consensus that they owned all bitcoin, and embed that into the blockchain. But as the number of nodes grows this becomes less practical. A realistic problem is that bitcoin operates without any central authority. Because of this, anyone making an error with a transaction on their wallet has no recourse.
If you accidentally send bitcoins to the wrong person or lose your password there is nobody to turn to. Of course, the eventual arrival of practical quantum computing could break it all. Much cryptography relies on mathematical calculations that are extremely hard for current computers to do, but quantum computers work very differently and may be able to execute them in a fraction of a second. Mining is the process that maintains the bitcoin network and also how new coins are brought into existence.
The first miner to solve the next block broadcasts it to the network and if proven correct is added to the blockchain. That miner is then rewarded with an amount of newly created bitcoin. Inherent in the bitcoin software is a hard limit of 21 million coins. There will never be more than that in existence. The total number of coins will be in circulation by Roughly every four years the software makes it twice as hard to mine bitcoin by reducing the size of the rewards.
When bitcoin was first launched it was possible to almost instantaneously mine a coin using even a basic computer. Now it requires rooms full of powerful equipment, often high-end graphics cards that are adept at crunching through the calculations, which when combined with a volatile bitcoin price can sometimes make mining more expensive than it is worth.
Miners also choose which transactions to bundle into a block, so fees of a varying amount are added by the sender as an incentive. Once all coins have been mined, these fees will continue as an incentive for mining to continue.
This is needed as it provides the infrastructure of the Bitcoin network. In the domain name. It set out the theory and design of a system for a digital currency free of control from any organisation or government. The central bank must be trusted not to debase the currency, but the history of fiat currencies is full of breaches of that trust.
The following year the software described in the paper was finished and released publicly, launching the bitcoin network on 9 January
Bitcoins can be transferred electronically and practically instantly and have historically had low transaction fees, though this is something that has recently changed. Only 21 million bitcoins can ever be created in order to protect the value of the bitcoin system. Bitcoins can be mined using computer software and a mathematical formula designed by the Bitcoin founder Satoshi Nakamoto.
Miners use the computer software to follow the mathematical formula to produce bitcoins. The mathematical formula is freely available for anyone to check and the software used is open source, meaning anyone can check it. Bitcoins are created as a reward for mining, they can be exchanged for other currencies, products or services. There are certain rules governing the creation of bitcoins; miners cannot just keep producing bitcoins as they please. Because only 21 million bitcoins can ever be produced by miners, the value of the system is preserved and the value of the bitcoins fluctuates wildly, depending on supply and demand.
The smallest divisible bitcoin amount is one hundred millionth and is called a Satoshi after the founder of bitcoin. Bitcoin transactions are sent to and from Bitcoin wallets, which is where your bitcoins are stored electronically. Bitcoin transactions are completely transparent, any bitcoin transaction can be traced back to the point where the bitcoins were produced. However bitcoin is completely anonymous as bitcoin addresses are not linked to names, addresses or other personally identifying information and any one user can hold multiple bitcoin addresses.

Bitcoin suffered a collapse this afternoon before bouncing back in less than 15 minutes. Keep up to date with the top cryptos in January As regulators in major economies provided clarity on the legality of Bitcoin and other cryptocurrencies, a large number of Bitcoin exchanges established banking connections, making it easy to convert local currency to and from bitcoin.
Other businesses established robust custodial services, making it easier for institutional investors to gain exposure to the asset as a growing number of high-profile investors signaled their interest. At its most basic level, Bitcoin is useful for transacting value outside of the traditional financial system. People use Bitcoin to, for example, make international payments that are settled faster, more securely, and at lower transactional fees than through legacy settlement methods such as the SWIFT or ACH networks.
In the early years, when network adoption was sparse, Bitcoin could be used to settle even small-value transactions, and do so competitively with payment networks like Visa and Mastercard which, in fact, settle transactions long after point of sale. However, as Bitcoin became more widely used, scaling issues made it less competitive as a medium of exchange for small-value items.
In short, it became prohibitively expensive to settle small-value transactions due to limited throughput on the ledger and the lack of availability of second-layer solutions. This supported the narrative that Bitcoin's primary value is less as a payment network and more as an alternative to gold, or 'digital gold. In this regard, the investment thesis is that Bitcoin could replace gold and potentially become a form of 'pristine collateral' for the global economy.
Another popular narrative is that Bitcoin supports economic freedom. It is said to do this by providing, on an opt-in basis, an alternative form of money that integrates strong protection against 1 monetary confiscation, 2 censorship, and 3 devaluation through uncapped inflation. Note that this narrative is not mutually exclusive from the 'digital gold' narrative. Read more: How does governance work in Bitcoin?

Instead, the network consists of willing participants who agree to the rules of a protocol which takes the form of an open-source software client. Changes to the protocol must be made by the consensus of its users and there is a wide array of contributing voices including 'nodes,' end users, developers, 'miners,' and adjacent industry participants like exchanges, wallet providers, and custodians.
This makes Bitcoin a quasi-political system. Of the thousands of cryptocurrencies in existence, Bitcoin is arguably the most decentralized, an attribute that is considered to strengthen its position as pristine collateral for the global economy.
