How to get a bitcoin wallet
To cut through some of the confusion surrounding bitcoin, we need to separate it into two components. On the one hand, you have bitcoin-the-token, a snippet of code that represents ownership of a digital concept — sort of like a virtual IOU.
On the other hand, you have bitcoin-the-protocol, a distributed network that maintains a ledger of balances of bitcoin-the-token.
The system enables payments to be sent between users without passing through a central authority, such as a bank or payment gateway. It is created and held electronically. It was the first example of what we today call cryptocurrencies, a growing asset class that shares some characteristics of traditional currencies, with verification based on cryptography. The idea was to produce a means of exchange, independent of any central authority, that could be transferred electronically in a secure, verifiable and immutable way.
Bitcoin can be used to pay for things electronically, if both parties are willing. No single institution controls the bitcoin network. It is maintained by a group of volunteer coders , and run by an open network of dedicated computers spread around the world.
This attracts individuals and groups that are uncomfortable with the control that banks or government institutions have over their money. In electronic fiat currencies, this function is fulfilled by banks, which gives them control over the traditional system.
With bitcoin, the integrity of the transactions is maintained by a distributed and open network, owned by no-one. Fiat currencies dollars, euros, yen, etc. Holders of the currency and especially citizens with little alternative bear the cost. With bitcoin, on the other hand, the supply is tightly controlled by the underlying algorithm.
A small number of new bitcoins trickle out every hour, and will continue to do so at a diminishing rate until a maximum of 21 million has been reached. This makes bitcoin more attractive as an asset — in theory, if demand grows and the supply remains the same, the value will increase. While senders of traditional electronic payments are usually identified for verification purposes, and to comply with anti-money laundering and other legislation , users of bitcoin in theory operate in semi-anonymity.
When a transaction request is submitted, the protocol checks all previous transactions to confirm that the sender has the necessary bitcoin as well as the authority to send them.
The system does not need to know his or her identity. In practice, each user is identified by the address of his or her wallet. Transactions can, with some effort, be tracked this way. Furthermore, most exchanges are required by law to perform identity checks on their customers before they are allowed to buy or sell bitcoin, facilitating another way that bitcoin usage can be tracked. Since the network is transparent, the progress of a particular transaction is visible to all.
While this may disquiet some, it does mean that any transaction on the bitcoin network cannot be tampered with. The smallest unit of a bitcoin is called a satoshi. It is one hundred millionth of a bitcoin 0. This could conceivably enable microtransactions that traditional electronic money cannot.

CoinDesk is an independent operating subsidiary of Digital Currency Group, which invests in cryptocurrencies and blockchain startups. But how? You can pay for them in a variety of ways, ranging from hard cash to credit and debit cards to wire transfers, or even with other cryptocurrencies, depending on who you are buying them from and where you live.
The first step is to set up a wallet to store your bitcoin — you will need one, whatever your preferred method of purchase. This could be an online wallet either part of an exchange platform, or via an independent provider , a desktop wallet, a mobile wallet or an offline one such as a hardware device or a paper wallet.
Even within these categories of wallets there is a wide variety of services to choose from, so do some research before deciding on which version best suits your needs. You can find more information on some of the wallets out there, as well as tips on how to use them, here and here. If you lose them, you lose access to the bitcoin stored there. Cryptocurrency exchanges will buy and sell bitcoin on your behalf. As with wallets, it is advisable to do some research before choosing — you may be lucky enough to have several reputable exchanges to choose from, or your access may be limited to one or two, depending on your geographical area.
Other high-volume exchanges are Coinbase , Bitstamp and Poloniex , but for small amounts, most reputable exchanges should work well. Note: at time of writing, the surge of interest in bitcoin trading is placing strain on most retail buy and sell operations, so a degree of patience and caution is recommended. With the clampdown on know-your-client KYC and anti-money-laundering AML regulation, many exchanges now require verified identification for account setup. This will usually include a photo of your official ID, and sometimes also a proof of address.
Most exchanges accept payment via bank transfer or credit card, and some are willing to work with Paypal transfers. Each exchange has a different procedure for both setup and transaction, and should give you sufficient detail to be able to execute the purchase. If not, consider changing the service provider. Once the exchange has received payment, it will purchase the corresponding amount of bitcoin on your behalf, and deposit them in an automatically generated wallet on the exchange.
This can take minutes, or sometimes hours due to network bottlenecks. If you wish recommended , you can then move the funds to your off-exchange wallet. Platforms such as LocalBitcoins will help you to find individuals near you who are willing to exchange bitcoin for cash. Also, LibertyX lists retail outlets across the United States at which you can exchange cash for bitcoin. And WallofCoins , Paxful and BitQuick will direct you to a bank branch near you that will allow you to make a cash deposit and receive bitcoin a few hours later.
ATMs are machines that will send bitcoin to your wallet in exchange for cash. Coinatmradar can help you to find a bitcoin ATM near you. Note: specific businesses mentioned here are not the only options available, and should not be taken as a recommendation.

Actually, a wallet usually holds several private keys, and many bitcoin investors have several wallets. Electronic wallets can be downloaded software, or hosted in the cloud.
The former is simply a formatted file that lives on your computer or device, that facilitates transactions. Hosted cloud-based wallets tend to have a more user-friendly interface, but you will be trusting a third party with your private keys.
Installing a wallet directly on your computer gives you the security that you control your keys. Most have relatively easy configuration, and are free. The disadvantage is that they do require more maintenance in the form of backups. If your computer gets stolen or corrupted and your private keys are not also stored elsewhere, you lose your bitcoin.
They also require greater security precautions. If your computer is hacked and the thief gets a hold of your wallet or your private keys, he also gets hold of your bitcoin. The original software wallet is the Bitcoin Core protocol, the program that runs the bitcoin network. As you can guess, this takes up a lot of memory — at time of writing, over GB. Exodus can track multiple assets with a sophisticated user interface.
Some such as Jaxx can hold a wide range of digital assets, and some such as Copay offer the possibility of shared accounts. Online or cloud-based wallets offer increased convenience — you can generally access your bitcoin from any device if you have the right passwords.
All are easy to set up, come with desktop and mobile apps which make it easy to spend and receive bitcoin, and most are free. The disadvantage is the lower security. Some leading online wallets are attached to exchanges such as Coinbase and Blockchain. Some offer additional security features such as offline storage Coinbase and Xapo.
Mobile wallets are available as apps for your smartphone, especially useful if you want to pay for something in bitcoin in a shop, or if you want to buy, sell or send while on the move.
All of the online wallets and most of the desktop ones mentioned above have mobile versions, while others — such as Abra , Airbitz and Bread — were created with mobile in mind. Hardware wallets are small devices that occasionally connect to the web to enact bitcoin transactions. They are extremely secure, as they are generally offline and therefore not hackable. They can be stolen or lost, however, along with the bitcoins that belong to the stored private keys. Some large investors keep their hardware wallets in secure locations such as bank vaults.
Trezor , Keepkey and Ledger and Case are notable examples. Perhaps the simplest of all the wallets, these are pieces of paper on which the private and public keys of a bitcoin address are printed.
They are, however, easier to lose. With services such as WalletGenerator , you can easily create a new address and print the wallet on your printer. Send some bitcoin to that address, and then store it safely or give it away. See our tutorial on paper wallets here. The safest option is a hardware wallet which you keep offline, in a secure place.
That way there is no risk that your account can be hacked, your keys stolen and your bitcoin whisked away. The least secure option is an online wallet, since the keys are held by a third party.
It also happens to be the easiest to set up and use, presenting you with an all-too-familiar choice: convenience vs safety. Whatever option you go for, please be careful.

In case of bitcoin and cryptocurrencies derived from it, the cryptocurrency is decentrally stored and maintained in a publicly available ledger called the blockchain. A cryptocurrency wallet, comparable to a bank account, contains a pair of public and private cryptographic keys. A public key allows for other wallets to make payments to the wallet's address, whereas a private key enables the spending of cryptocurrency from that address. Wallets can either be digital apps or be hardware based.
Multisignature wallets require multiple parties to sign a transaction for any digital money can be spent. With a deterministic wallet a single key can be used to generate an entire tree of key pairs. The generated mnemonic sentence or word seed is simply a more human-readable way of expressing the key used as the root, as it can be algorithmically converted into the root private key.
Those words, in that order, will always generate exactly the same root key. A word phrase could consist of 24 words like: begin friend black earth beauty praise pride refuse horror believe relief gospel end destroy champion build better awesome. That single root key is not replacing all other private keys, but rather is being used to generate.
All the addresses still have different private keys, but they can all be restored by that single root key. The private keys to every address it has and will ever give out can be recalculated given the root key. That root key, in turn, can be recalculated by feeding in the word seed.
The mnemonic sentence is the backup of the wallet. If a wallet supports the same mnemonic sentence technique, then the backup can also be restored on another software or hardware wallet. A mnemonic sentence is considered secure. The BIP standard creates a bit seed from any given mnemonic. The set of possible wallets is 2 Every passphrase leads to a valid wallet.
If the wallet was not previously used it will be. In a non-deterministic wallet, each key is randomly generated on its own accord, and they are not seeded from a common key.
Therefore, any backups of the wallet must store each and every single private key used as an address, as well as a buffer of or so future keys that may have already been given out as addresses but not received payments.
