Note (September 2026): This guide has been corrected and expanded. Earlier text said hardware wallets need their batteries changed and called paper wallets hacker proof; many hardware wallets have no battery at all, and the Bitcoin Wiki now describes paper wallets as an obsolete and unsafe storage method.
The main types of bitcoin wallets are online (web), mobile, desktop, hardware and paper wallets. They fall into two groups: hot wallets, which stay connected to the internet and suit everyday spending, and cold wallets, which keep the private keys offline for long-term savings. A wallet can also be custodial, where a company holds the keys, or non-custodial, where the owner does.
Key Takeaways
- A bitcoin wallet stores private keys, not coins; the bitcoin itself always stays on the blockchain.
- Hot wallets (online, mobile, desktop) are convenient for small, frequent payments; cold wallets (hardware, offline devices) suit long-term holdings.
- With a custodial wallet a company holds the keys, so its failure or hack can freeze customer funds, as the Mt. Gox (2014) and FTX (2022) collapses showed.
- Most modern wallets can be restored from a seed phrase of 12 to 24 words defined by the BIP39 standard; anyone who sees that phrase can take the funds.
- According to the FBI’s 2025 Internet Crime Report, Americans reported $11.366 billion in losses in complaints involving cryptocurrency in 2025.
Bitcoin is the digital currency that is taking the world by storm. Today, many are accepting bitcoins. However, the bitcoins you purchase must be stored safely.
A bitcoin wallet is the tool used to keep bitcoin safe. Strictly speaking, the wallet does not hold the coins: the bitcoin stays on the blockchain, and the wallet stores the private keys that allow the owner to spend it. There are different types of bitcoin wallets available in the digital world. You must choose the one that is safer for you to buy.
Different Types Of Crypto Wallets
There are two types of wallets: the hot wallet and the other is the cold wallet. The difference between them is whether they are connected to the internet to store the thenewsspy digital currency. Hot wallets are less secure as you must connect to the internet. It poses a serious security threat. However, it is user-friendly.
The cold wallet is used as cold storage to keep the cryptocurrencies. The digital currency would be stored offline to boost security. Cold storage works more like a savings vault than the cash carried in a pocket wallet; it is the hot wallet that plays the role of everyday spending money.
The hot wallet can be used for day to day transactions. On the other hand, a cold wallet would be used to store bitcoins. These are for savings.
This guide divides wallets into five common types, based on where the private keys are kept, and each type offers a different level of security. Now, let us take a close look at each wallet and its pros and cons.
1] Online wallet
You can access the online wallet through the web browser. The online wallets can be called as hot wallets. The wallet can be on the mobile or on the desktop.
However, it is recommended not to keep all the bitcoins in one place and in one wallet to avoid security threats. The online wallets are highly attractive to the attackers, and these are almost like honey pots to them.
Pros
- Quick to complete the transaction.
- Best to keep small amounts.
- Manage different types of digital currencies in one wallet.
- Offer privacy.
Cons
- Prone to phishing and other security vulnerabilities.
- With a custodial online wallet, the private keys are kept on the provider’s servers, so the user has to trust that company to stay solvent and secure.
2] Mobile wallets
You can store the bitcoins on the mobile wallet. This gives access to the bitcoins as long as your mobile is with you. It runs with the help of the internet and is also prone to many security threats.
Pros
- Easy to use and send payments in a matter of seconds unlike other payment options.
- Scan QR code and make payments through bitcoins.
- Offer privacy.
Cons
- Insecure devices and additional encryption are required.
- The phone is prone to virus or key loggers.
3] Desktop wallet
The desktop wallet is known to be a little secured compared to the online and mobile wallets. However, if you are getting connected to the internet, it is prone to security threats. If you are using a laptop to store the bitcoins offline, it is considered cold storage and highly secure. You can use the old laptop to store bitcoins.
Pros
- Simple to use.
- If you are not connecting to the internet, then it is highly safe.
- Private keys are not kept on the server.
- Offer privacy.
Cons
- When connected to the internet, it is prone to security threats.
- If you are giving computer for repair, the technicians may steal the coins.
- If you fail to back up the bitcoins while formatting, you lose them.
- People can steal the coins through key loggers.
4] Hardware wallet
This is not so user-friendly when compared to the online wallet, mobile wallet, and desktop wallet. However, these are highly secure compared to the hot wallets and simple to use compared to the paper-based wallet.
Hardware wallets do not need regular battery changes. According to Trezor’s model comparison, the Trezor Safe 3 and Trezor Safe 5 have no battery and connect with a USB-C cable, while the Bluetooth-capable Trezor Safe 7 has a built-in rechargeable battery. Many models look like a USB flash drive, but the device stores the private keys rather than the coins; it signs transactions internally so the keys are never exposed to the connected computer. You can store a lot of cryptocurrencies on this wallet. You do not have to take this often, whenever you need some, you can transfer to the online wallet and start using it.
Pros
- Secure way to store bitcoins.
- Stronger security.
- Cons: the device has to be bought, and losing it without a proper backup of the recovery phrase can make the funds unrecoverable.
- Challenging for the beginners to learn and use.
5] Paper wallet
It is a cold wallet where the bitcoins would be in the form of paper. The Bitcoin Wiki now describes paper wallets as an obsolete and unsafe method that was popular between 2011 and 2016, and recommends seed-phrase wallets instead.
Pros
- Kept offline, so it cannot be reached remotely once printed, although printers, damaged QR codes and single-address reuse create other risks.
- Do not need to store on any third-party server or computer.
- Private keys are with you.
Cons
- Put a lot of efforts to move the cryptocurrencies.
- Must have technical knowledge.
What Is a Bitcoin Wallet?
A bitcoin wallet is a device, physical medium, program or online service that stores the public and private keys used to send and receive bitcoin. The public side produces addresses that others can pay; the private key signs transactions and proves ownership. Losing the private key means losing access to the bitcoin permanently.
Bitcoin itself was described in a white paper posted on October 31, 2008, and the network went live on January 3, 2009, when Satoshi Nakamoto mined the genesis block. The first wallet program was released in January 2009, and Bitcoin Core remains the best-known Bitcoin software. Each bitcoin divides into 100 million satoshis, and the total supply is capped at 21 million coins.
Hot Wallet vs Cold Wallet: Comparison Table
A hot wallet keeps its keys on a device connected to the internet, while a cold wallet keeps them offline. The table compares the five wallet types covered above.
| Wallet type | Hot or cold | Who usually holds the keys | Best suited to | Main risk |
|---|---|---|---|---|
| Online (web) wallet | Hot | Often the provider (custodial) | Small balances, quick trades | Provider hack, failure or account phishing |
| Mobile wallet | Hot | User or provider, depending on the app | Everyday payments, QR codes | Lost or damaged phone, malware, fake apps |
| Desktop wallet | Hot (cold if kept offline) | User | Regular use with more control | Malware, keyloggers, lost backups |
| Hardware wallet | Cold | User | Long-term savings, larger sums | Losing the device and the recovery phrase |
| Paper wallet | Cold | User | Legacy method, not recommended today | Printing leaks, damage, change-address mistakes |
Custodial vs Non-Custodial Wallets: Who Holds the Keys?
A custodial wallet is one where a company, usually an exchange, holds the private keys on the customer’s behalf. A non-custodial wallet gives the user the keys, so no third party can freeze or take the funds, but the user alone is responsible for securing and backing up the wallet. Bitcoin.org’s wallet guide makes the same distinction.
Custody risk is not theoretical. Mt. Gox, which by April 2013 was handling over 70% of the world’s bitcoin trades, suspended all trading on February 24, 2014, filed for bankruptcy protection in Tokyo on February 28, 2014, and reported about 850,000 bitcoins lost (it later found 199,999.99 of them in an old wallet). FTX and more than 100 affiliates filed for bankruptcy in Delaware on November 11, 2022, after customers became unable to withdraw deposits; founder Sam Bankman-Fried was convicted of defrauding FTX customers on November 2, 2023, and sentenced to 25 years in prison in March 2024.
Large platforms remain targets. On February 21, 2025, attackers took roughly 400,000 ether, worth about $1.4 to $1.5 billion, from the exchange Bybit by exploiting its multi-signature wallet system through compromised infrastructure at a third-party provider, Safe{Wallet}; the FBI attributed the theft to North Korea. Anyone who keeps coins on an exchange should read the platform’s custody terms, and our list of crypto exchanges and apps with low fees is a starting point for comparing them.
Other Bitcoin Wallet Types Worth Knowing
Full-node and lightweight wallets
A full-node wallet, such as Bitcoin Core, downloads and verifies the entire blockchain. A lightweight wallet uses simplified payment verification (SPV) and does not need the full chain. Electrum, released in 2011, is a well-known lightweight, non-custodial wallet for Bitcoin and the Lightning Network, available for Windows, macOS, Linux and Android.
Lightning wallets
The Lightning Network is a second-layer payment network built on Bitcoin for fast payments that do not each need to be recorded on the blockchain. Its white paper was published by Joseph Poon and Thaddeus Dryja in February 2015, and Lightning Labs launched the network in 2018. Wallets that support Lightning include Phoenix, Cash App and Strike. As of March 2026, Wikipedia lists the public network at more than 17,000 nodes with roughly 4,900 BTC of capacity.
Multi-signature wallets
A multi-signature (multisig) wallet requires more than one party or key to authorize a transaction, for example two of three keys held on separate devices or by separate people. Multisig removes a single point of failure, although the Bybit theft shows that the software used to approve multisig transactions must be secured as well.
Hierarchical deterministic (HD) wallets
An HD wallet, described publicly in the BIP32 proposal, generates all of its keys from one master seed, so a single backup can restore every address in the wallet.
Brain wallets
A brain wallet derives the key from a memorized passphrase. Brain wallets are vulnerable to password-cracking attacks and are not a safe way to store bitcoin.
What Is a Seed Phrase and Why Does It Matter?
A seed phrase (also called a recovery phrase or mnemonic) is a list of words that can rebuild a wallet’s keys on any compatible device. The BIP39 standard, assigned on September 10, 2013, defines phrases of 12, 15, 18, 21 or 24 words drawn from a 2,048-word list, with an optional extra passphrase.
Whoever holds the seed phrase controls the bitcoin, so it should be written down offline, stored somewhere safe from fire and water, and never typed into a website, chat or email. Our guide on how to secure a bitcoin seed phrase covers storage options in detail.
How to Choose the Right Bitcoin Wallet
- Decide what the bitcoin is for. Spending money belongs in a hot wallet; long-term savings belong in cold storage.
- Decide who should hold the keys. A custodial service is simpler but adds counterparty risk; a non-custodial wallet puts full responsibility on the owner.
- Check the platform. Bitcoin.org groups wallets by mobile, desktop, hardware and web, and notes that app stores can delist a mobile wallet, which can make future updates difficult to get.
- Download only from the official source. Fake wallet apps and look-alike websites are a common way to steal seed phrases.
- Back up before funding. Write down the seed phrase, then test a small receive-and-send before moving larger amounts.
- Add layers of protection. Bitcoin.org suggests a strong passphrase, moving most funds to cold storage, and two-factor or multifactor authentication.

How to Keep Bitcoin Safe From Scams
Wallet security is only half of the picture, because many losses come from people being tricked into sending crypto. According to the FBI’s 2025 Internet Crime Report, the Internet Crime Complaint Center (IC3) received 181,565 complaints involving cryptocurrency in 2025, with $11.366 billion in reported losses, a 22% rise from 2024. Cryptocurrency investment fraud alone accounted for $7.228 billion, and recovery scams, which target people who have already lost money, drew 10,516 complaints and $1.4 billion in losses.
The US Federal Trade Commission warns that cryptocurrency payments do not come with the legal protections of credit and debit cards, are typically not reversible, and are not insured by the government like dollars in an FDIC-insured bank account. The FTC’s rule of thumb is that only scammers demand payment in cryptocurrency. Victims in the US can report fraud to the FTC at ReportFraud.ftc.gov, to the IC3, the SEC or the CFTC, and to the exchange involved. Our article on avoiding scams when withdrawing crypto to a bank account covers the cash-out stage.
Common Bitcoin Wallet Mistakes
- Storing the seed phrase digitally, such as in a photo, cloud note or email, where malware or a breached account can expose it.
- Keeping everything on an exchange, which exposes the whole balance to that company’s failure or hack.
- Having no backup. Losing a private key means losing access permanently, and Wikipedia cites an estimate that around 20% of all bitcoins are lost.
- Partly spending from a paper wallet. The Bitcoin Wiki says users mistakenly believe the remainder is still on the paper when it has moved to a change address; the safer method is to sweep the whole balance into a modern wallet.
- Sharing the recovery phrase with anyone claiming to be support staff, since the phrase gives full control of the funds.

Frequently Asked Questions
What are the 5 types of bitcoin wallets?
The five common types of bitcoin wallets are online (web) wallets, mobile wallets, desktop wallets, hardware wallets and paper wallets. The first three are usually hot wallets connected to the internet; hardware and paper wallets are cold storage that keeps the private keys offline.
What is the difference between a hot wallet and a cold wallet?
A hot wallet keeps its private keys on an internet-connected device, which makes payments fast but exposes it to online attacks. A cold wallet keeps the keys offline, which is slower to use but much harder to attack remotely, so it suits long-term savings.
Can a bitcoin wallet be hacked?
Yes. Hot wallets can be compromised by malware, phishing or a breach at the provider, and even large exchanges have lost funds, such as Bybit in February 2025. Cold wallets are far harder to attack remotely, but a stolen or photographed seed phrase gives full access to the funds.
What happens if I lose my bitcoin wallet?
If the device is lost but the seed phrase is backed up, the wallet can be restored on a new device and the bitcoin is still available. If both the device and the seed phrase are lost, the bitcoin cannot be recovered, because nobody else holds the private key.
Are paper wallets still safe to use?
Paper wallets are no longer recommended. The Bitcoin Wiki calls them an obsolete and unsafe method that was popular between 2011 and 2016, citing printer risks, damaged QR codes, address reuse and change-address errors, and it recommends seed-phrase wallets instead.
Do I need a wallet to own bitcoin?
Owning bitcoin directly requires a wallet, either one the owner controls or a custodial account at an exchange. Since January 2024, when the first 11 US spot bitcoin exchange-traded funds began trading, investors have also been able to get bitcoin price exposure through a brokerage account without holding any keys.
