To do away with central authorities, cryptocurrencies use blockchains to record their transactions.

A blockchain is a ledger that is simultaneously stored and updated on thousands of independent computers across the globe. While I will use bitcoin as an example in this post, a lot of the concepts discussed here apply to other cryptocurrencies. When people want to send you bitcoins, they will use your bitcoin address, a unique string of alphanumeric characters. Each approved payment is added to the blockchain and contains the addresses of the sender and the receiver of the transaction. How can you prove bitcoins stored on an address belong to you? Every bitcoin address is associated with a pair of public and private cryptographic keys.

Data encrypted with a public key can only be decrypted with the private key. People usually publish their public key to allow others to encrypt and send them confidential information. They keep the private key to themselves and use it to decipher data encrypted with their public key. The reverse is also true: Data encrypted with a private key can only be decrypted with the public key. Since my public key is already known, anyone can validate my signature by trying to decrypt it with my public key.

Back to bitcoin transactions. Before I can send bitcoins from an address, I have to prove that I own them. Once that is verified, the computers maintaining the bitcoin blockchain will approve and register my transaction. This brings us to the key point about bitcoin ownership: Whoever holds the private key of an address owns the bitcoins stored at that address.

And this is what the bitcoin wallet does. A bitcoin wallet simply stores the address and the public and private keys to one or more bitcoin addresses.

How you store your private keys will determine the security of your bitcoin funds. And each type of bitcoin wallet has its benefits and tradeoffs. For instance, online wallets are easier to use than other types of wallets. You can access them from a browser on any device as long as you can remember your username and password.

And they have plenty of good features such as quickly buying, selling, and trading cryptocurrencies. However, they store your private keys on a central server, which makes them a bit like banks. Also, if you fall victim to a phishing attack , an attacker will be able to access your wallet and steal your bitcoins because your private key is stored online. Online wallet companies usually do a good job of keeping user accounts secure, but they occasionally get hit by data breaches, where hackers steal all the private keys and cryptocurrencies of their users.

Software wallets can be installed on any kind of device. You get to keep your private keys and privacy. The security of software wallets is also complicated. If your device gets hacked with file-stealing malware, an attacker might be able to steal your private key. And if your device gets destroyed or lost , you will lose your bitcoins. Hardware wallets have an associated web, mobile, or desktop application that enables you to monitor your bitcoin addresses and spend bitcoins.

Securing your wallet

Private keys are stored in the hardware wallet and never leave the device. When you want to confirm a payment, the transaction is signed inside the hardware wallet and the output is sent to the app.

They also require you to make a small upfront investment to buy the device. And like software wallets, if you lose your device, forget your PIN code, or forget your recovery seed, your bitcoins are gone. Paper wallets are completely offline, which makes them the most digitally secure type of wallet. But paper wallets are very hard to use.

Instead, they get a confirmation score that indicates how hard it is to reverse them see table. Each confirmation takes between a few seconds and 90 minutes, with 10 minutes being the average. If the transaction pays too low a fee or is otherwise atypical, getting the first confirmation can take much longer.

Bitcoin is an experimental new currency that is in active development. Each improvement makes Bitcoin more appealing but also reveals new challenges as Bitcoin adoption grows. During these growing pains you might encounter increased fees, slower confirmations, or even more severe issues. Be prepared for problems and consult a technical expert before making any major investments, but keep in mind that nobody can predict Bitcoin's future. Bitcoin is not an official currency. That said, most jurisdictions still require you to pay income, sales, payroll, and capital gains taxes on anything that has value, including bitcoins.

Securing your wallet Like in real life, your wallet must be secured. Bitcoin price is volatile The price of a bitcoin can unpredictably increase or decrease over a short period of time due to its young economy, novel nature, and sometimes illiquid markets.
