WALLET & SECURITY
Choosing the Right Hardware Wallet: A Complete Investor Guide
When it comes to securing cryptocurrency, hardware wallets are the gold standard for investors. They provide a cold storage option for investors, meaning your private keys never touch the internet; protecting your assets from hacks, malware, and phishing attempts.
But not all hardware wallets are created equal. The two industry leaders, Ledger and Trezor, dominate the market, each offering different philosophies, ecosystems, and security models through their hardware wallets. Beyond them, new market challengers like Coldcard, BitBox, Tangem and SafePal have introduced innovative features designed for specific users.
This guide breaks down each of the major hardware wallets, explaining how they work, how they differ, and which one might best suit your setup.
What Is a Hardware Wallet?
A hardware wallet is a physical device that securely stores your crypto private keys offline.
When you send or sign a transaction:
- The transaction is created on your computer or phone.
- It’s sent to the hardware wallet for offline signature.
- The wallet signs the transaction internally (without exposing the private key).
- The signed transaction is sent back to the blockchain network.
Your keys never leave the device, meaning even if your computer is compromised, your funds stay secure.
Hardware wallets are most commonly used by long-term holders, traders, and institutions who prioritize self-custody and security.

Ledger Wallet
What is Ledger: Company Background & Evolution
When it comes to safely storing crypto, Ledger is one of the most recognised names in the space. Founded in 2014, Ledger built its reputation around one goal; helping people take full ownership of their digital assets through secure hardware wallets.
At its core, Ledger is a cold storage device. That means it keeps your private keys offline, away from the internet and potential hacks. The device itself acts as your personal vault, where transactions must be approved physically by you before anything moves on-chain.
Ledger’s product line has expanded from their initial Nano wallets into Nano X, Nano S Plus, and now into their newer models like Ledger Stax and the Ledger Flex. From an enterprise side, Ledger also offers institutional products (Ledger Vault, Ledger Enterprise) beyond consumer hardware.
‘Ledger Live’ is the ecosystem’s software hub. The companion App allows you to view your portfolio, send & receive assets, install apps for each token, and even stake certain cryptocurrencies directly, all while your private keys never leave the device.
Beyond being a wallet, Ledger’s ecosystem also integrates security layers, educational content, and institutional-grade solutions for businesses. Their Secure Element chips (the same kind used in passports and credit cards) add another level of protection against physical tampering or malware.
Ledger’s strength lies in control and independence. You’re no longer trusting an exchange to hold your funds. Instead, you’re holding them yourself. For everyday investors, that’s the difference between having crypto and owning it.
Hardware Models & Features
Ledger offers several hardware wallet models, each targeted at slightly different use-cases.
Models
- Ledger Nano S Plus – The budget/entry model; USB-C, compact, supports many assets.
- Ledger Nano X – Premium model: Bluetooth mobile connectivity, larger app capacity (more coins/tokens), rechargeable battery in some cases.
- Ledger Stax – More recent, design-forward model with touchscreen/E-Ink display, and an emphasis on usability and premium features
- Ledger Flex – Another newer model, focusing on modularity or advanced features. (And our personal favourite).
Feature Highlights
- Secure Element Chip (tamper-resistant hardware) for storing private keys.
- Companion appLedger Live to install apps for individual cryptocurrencies, send/receive, stake tokens, etc
- Multi-asset support: Big list of coins, tokens, networks.
- Mobile + Desktop compatibility (especially with Nano X)
- Recovery via seed phrase: When you set up a Ledger device, you generate a 24-word (or sometimes 12/24) seed phrase which allows you to recover funds if the device is lost.
Security Model: What Makes Ledger Secure
Ledger’s entire ecosystem is built on the idea of security through isolation; keeping your private keys completely separated from online environments where most hacks occur.
- Secure Element (SE) Chip: Every Ledger device is powered by a Secure Element chip, the same type of chip used in passports, credit cards, and banking systems. This chip is designed to protect against both digital and physical attacks, meaning even if your computer is compromised, your private keys remain safe inside the device.
- Secure OS + Attestation: Ledger’s firmware and operating system, known as BOLOS (Blockchain Open Ledger Operating System), creates a secure execution environment where each crypto app runs independently. This sandboxed approach means a vulnerability in one coin’s app cannot compromise the rest of your wallet.
- PIN protection / device control: Ledger devices undergo third-party security audits and follow strict manufacturing processes that prevent tampering before the product reaches you. Combined with Ledger’s PIN protection, passphrase support, and recovery seed system, the result is a multi-layered security model that’s trusted by both retail users and institutions.
- Seed phrase backup: Your recovery phrase is the ultimate fall-back, so Ledger emphasises safe storage of that. Specifically, it’s recommended to keep a paper copy of your seed phrase stored somewhere safe; away from water or fire damage.
- Firmware updates: The company issues regular security patches, updates to firmware and Ledger Live. Users are urged to update to stay safe.
What this means: If you use the device correctly (buy from trusted source, initialise it yourself, keep recovery phrase safe, update firmware), your private keys are highly protected from most internet-based attacks.
Pros & Strengths of Ledger
Based on expert reviews and features, major strengths of Ledger include:
✅ Industry-Leading Security
Ledger uses Secure Element chips and its proprietary BOLOS operating system to isolate and protect private keys. This multi-layer security model is trusted by both retail users and institutions worldwide.
✅ Offline Protection (Cold Storage)
Private keys never touch the internet. All signing happens within the device, keeping funds safe even if your computer or phone is compromised.
✅ User Ownership and Control
Ledger gives you complete custody of your crypto. You approve every transaction physically, meaning no one — not even Ledger — can move your assets without your confirmation.
✅ Wide Asset Support

Cons & Limitations of Ledger
❌ Not Fully Open Source
While Ledger’s apps and interfaces are open-source, its firmware and Secure Element code are closed. This limits full community verification of its security processes.
❌ Requires Technical Understanding
Ledger is beginner-friendly overall, but initial setup still requires careful attention to recovery phrases, app installations, and firmware updates. Mistakes during setup can cause access issues later.
❌ Centralised Recovery Concerns
Ledger’s optional “Recover” feature raised privacy debates, as it involves encrypted key backups with third-party custodians. While optional, it created concern among users who prefer full decentralization.
❌ Physical Risk Still Exists
The device itself can be lost, stolen, or damaged. Without a correctly stored recovery phrase, assets on the wallet are permanently unrecoverable.
❌ Limited Mobile Usability (Nano S Plus)
The Nano S Plus lacks Bluetooth and requires a cable connection. Only the Ledger Nano X supports mobile pairing, which might be more convenient for on-the-go users.
❌ Price Point vs. Simpler Alternatives

How to Setup & Use your Ledger
Here’s a typical setup flow for using a Ledger hardware wallet:
- Purchase from official source – ensure sealed, new device.
- Connect to computer or mobile, download official Ledger Live from ledger.com.
- Initialise device – choose “Set up as new device”.
- Create PIN on the device.
- Write down your recovery seed phrase (24 words recommended) on the provided cards (or your metal backup) and store securely offline.
- Install apps for each cryptocurrency you want to hold via Ledger Live (e.g., Bitcoin, Ethereum, etc.).
- Send funds to your Ledger address – you receive a public address via device+app, verify on device screen, then send from exchange/hot wallet to your Ledger address.
- Regularly update firmware and software – ensure device and Ledger Live are updated; check for authenticity signs.
- For mobile use (Nano X, Stax) – pair with Bluetooth if required, but many experts recommend USB connection for maximum security.
- Safely store recovery phrase and safely move long-term holdings.
Remember: Your funds are only truly secure if your seed phrase is safe and private, and you verified device authenticity.
Trezor Wallet
What is Trezor: Company Background & Evolution
Trezor hardware wallets are another form of physical devices designed to store your crypto private keys offline (cold storage). They work by requiring physical confirmation on the device for transactions, meaning even if your computer is compromised, your keys aren’t exposed.
Founded in 2013 by SatoshiLabs (based in Prague, Czech Republic), Trezor launched with the world’s first consumer-hardware cryptocurrency wallet. The company emphasises open-source software and transparency in hardware wallet design as the core highlight.
Over the years Trezor has released multiple models (Model One, Model T, Safe 3, Safe 5) and expanded its ecosystem with the companion app Trezor Suite and integrations with third-party wallets. Their mission: give users full control of their digital assets, using hardware wallets that keep private keys offline.
Key components:
- The device itself: stores your seed, private keys offline.
- Companion software: Trezor Suite (for desktop; mobile support limited) to manage your portfolio, send/receive assets, view history
- Recovery / backup mechanism: Seed phrase and optional advanced backups (Shamir Backup, multi-share backup).
- Broad coin/token support: thousands of asset
Hardware Models & Features
Trezor offers multiple hardware models. Here is a breakdown:
Models
- Trezor Model One: Entry level. USB (micro-USB or USB-C depending region), basic display, supports many coins but less premium features.
- Trezor Model T: Flagship model with full-colour touchscreen, USB-C, advanced features (Shamir backup, microSD slot on some versions).
- Trezor Safe 3: A newer model with Secure Element (EAL6+) certification, open-source design, monochrome screen, USB-C.

- Open-source firmware and hardware design (for most models) allowing independent audits.
- Passphrase support (adds an extra word beyond seed phrase, enabling hidden wallet feature)
- Broad multi-currency support: Some models support 9,000+ coins/tokens.
- Recovery via standard seeds (12/24 words) and advanced backup (multi-share or Shamir on higher models).
Security Model: What Makes Ledger Secure
Trezor’s approach to security is built on transparency, simplicity, and open-source architecture. Unlike some competitors, every part of Trezor’s firmware and hardware design is fully auditable by the public, ensuring there are no hidden components or undisclosed code.
At its core, Trezor follows the same security principle as other cold wallets; your private keys never leave the device. Transactions are signed inside the wallet itself, so even if your connected computer is compromised, your crypto remains secure.
Trezor devices use a deterministic wallet structure (BIP32/BIP39/BIP44 standards), which means all your crypto accounts are generated from a single recovery seed phrase. This seed never touches the internet and can be backed up offline for complete recovery if the device is lost.
One key difference is Trezor’s focus on open-source firmware, allowing the global security community to verify and improve its code. This makes it highly transparent but also relies heavily on its physical protection measures, since unlike Ledger, Trezor does not use a “Secure Element” chip. Instead, it relies on its PIN protection, passphrase encryption, and physical confirmation process to secure transactions.
Each device runs on Trezor Core, its proprietary operating system that isolates wallet operations from external connections. When confirming a transaction, details must be manually verified on the Trezor’s screen before approval, ensuring you always see exactly what’s being signed.
To protect against physical theft, Trezor also includes anti-brute-force protections, wiping the device after too many incorrect PIN attempts. Optional Shamir Backup (a feature on the Model T) allows splitting your recovery seed into multiple shares, stored separately for added redundancy.
Pros & Strengths of Trezor
✅ Fully Open-Source Security Architecture
Trezor’s firmware, software, and hardware design are all open-source. This transparency allows independent security experts to review, verify, and improve its code; a major advantage for users who value decentralisation and trust through visibility.
✅ True Cold Storage (Offline at All Times)
Private keys never leave the device. All transactions are signed within Trezor itself, ensuring your crypto remains safe even if the computer or network it’s connected to is compromised.
✅ Simple and Intuitive Setup
Trezor’s interface and companion software (Trezor Suite) make setup straightforward. Users can manage multiple cryptocurrencies, view balances, and send or receive funds without technical knowledge.
✅ Industry-Standard Recovery System
Uses BIP39 recovery seed phrases, meaning you can restore your wallet on any compatible device if your Trezor is lost or damaged. The optional Shamir Backup (Model T) adds extra redundancy and resilience.
✅ PIN and Passphrase Protection
Trezor adds multiple layers of protection before access. A wrong PIN entry increases delay times exponentially, and adding a passphrase creates a hidden wallet for extra privacy and security.
✅ Transparent and Audited Development
Because its entire codebase is public, Trezor is continuously audited by security researchers and the community. This open model reduces hidden risks and ensures constant improvement.
✅ Long-Term Track Record and Reputation
As the world’s first hardware wallet (launched in 2014 by SatoshiLabs), Trezor has built a decade-long reputation for reliability and user trust in both retail and institutional settings.
Cons & Limitations of Trezor
❌ No Secure Element Chip
Unlike Ledger, Trezor doesn’t use a Secure Element — a dedicated chip found in high-security hardware like passports and payment cards. While its open-source model offers transparency, it also relies more heavily on the user’s physical and procedural security habits.
❌ Vulnerable to Physical Access Attacks
If an attacker gains physical access to your Trezor and has advanced technical tools, there is potential for extracting private keys through hardware-level attacks. This is why storing the device safely and using a passphrase is critical.
❌ Slightly Bulkier Interface Design
Trezor devices are functional and durable, but some users find them less compact and sleek compared to other wallets. It’s not a major flaw, but worth noting for portability and everyday use.
❌ Limited Mobile Compatibility
Trezor currently focuses on desktop software (Trezor Suite) and has limited native mobile app support compared to some competitors. This makes it less convenient for investors who manage portfolios on the go.
❌ Fewer Supported Assets Compared to Ledger
Trezor supports most major cryptocurrencies and tokens, but it lags behind Ledger in total asset count and third-party app integrations. Certain niche coins and DeFi tokens may require manual management through external interfaces.
❌ Price Point (Model T)
The Trezor Model T, while feature-rich with a touchscreen and Shamir Backup, is relatively expensive compared to entry-level hardware wallets.
How to Setup & Use your Trezor
Here’s a typical setup flow for using a Trezor hardware wallet:
- Purchase from the official Trezor Shop or authorised reseller. Avoid used/third-party side-sales.
- Connect the device to your computer (USB-C for newer models).
- Go to the official site and download Trezor Suite (or open the setup wizard).
- Follow setup: install firmware, create PIN, generate recovery seed.
- Write down your recovery seed (12/24 words) on paper or metal backup; never take a photo of your seed phrase.
- Optionally enable passphrase / hidden wallet.
- Install coin apps (via Trezor Suite or external wallet) for the assets you hold.
- To receive crypto: generate receive address on device (verify on hardware screen) then send from exchange/hot wallet.
- To send crypto: approve on device screen.
Update device firmware periodically and keep software (Trezor Suite) up to date.
(Also ensure you keep recovery seed safe, test your backup on a spare device sometimes)
The Ledger & Trezor lead the market as the two preferred hardware wallet choices that most crypto investors go with. But for those of you looking for a hardware wallet that specialises in a specific niche, here are a few strong shouts:
Coldcard Hardware Wallet

Cons & Limitations of Coldcard
❌ Bitcoin-Only Support
One person’s considered strength is another person’s limitation. Coldcard supports Bitcoin exclusively. While this focused design improves security, it means users holding altcoins or stablecoins will need a separate wallet solution for those assets.
❌ Steeper Learning Curve
Coldcard’s advanced security features, like PSBT files, multi-sig configurations, and microSD signing all require more technical understanding than plug-and-play wallets like Ledger or Trezor. It’s best suited for users who are comfortable learning detailed processes.
❌ Less User-Friendly Interface
Its small monochrome screen and basic button navigation get the job done but feel outdated compared to touchscreens and modern app interfaces. Functionality outweighs design here, but it’s not built for ease of use.
❌ No Native Mobile or Web App
Coldcard doesn’t integrate with any mobile applications or cloud-based software. All management happens through compatible desktop wallets like Sparrow or Electrum, which may not suit casual crypto investors.
❌ No Altcoin or DeFi Support
Since Coldcard is purely Bitcoin-focused, users can’t stake, swap, or interact with smart contracts directly from the device. For those invested in broader DeFi ecosystems, this is a major limitation.
❌ Manual Process for Transactions
Because it’s air-gapped, Coldcard requires transferring files via microSD cards for every transaction. This process maximises security but reduces convenience for those who move funds frequently.
❌ Niche Market Appeal
Its design philosophy prioritises maximum security over accessibility. While perfect for long-term Bitcoin holders, it’s overkill for beginners or casual investors looking for simplicity.
How to Setup & Use your Coldcard
1. Verify the device – Check tamper-evident bag number against Coldcard site. Then power on and confirm the firmware version matches the official release.
2. Create a new wallet – Select “Create Wallet”. Then write down the 24-word seed on paper only.
3. Set the Pin – Create the two part anti-phishing PIN
4. Make Backups of wallet in case of theft or damage – Insert microSD, choose “Backup Wallet” to create an encrypted backup file (Optional Step).
5. Pair with a desktop wallet – Install Sparrow or Electrum on your computer. Then export the XPUB from Coldcard to microSD. Finally, import the XPUB into the desktop wallet.
6. Receive your first Bitcoin – Generate a receive address in the desktop wallet. Verify the address on the Coldcard screen before sharing your public address to receive funds.
BitBox Hardware Wallet
What is BitBox: Company Background & Evolution
The Bitbox, natively known as BitBox02 is a hardware wallet designed to store your cryptocurrency private keys offline, meaning your keys are never exposed to the internet when making transactions or holding assets. Originating from Switzerland, the Bitbox comes in two main editions: a Multi-asset edition (supports many coins and tokens) and a Bitcoin-only edition (simplified firmware with a reduced attack surface). Manufactured by Shift Crypto AG, Bitbox promotes itself to be known for privacy-focused design and open-source firmware.
Key Features
Two Editions for Different Investors
BitBox02 comes in two models:

Having a specialised model designed for Bitcoin only is a real security benefit. Less code means fewer vulnerabilities. It’s ideal for long-term BTC holders who want maximum protection.
✅ Strong ecosystem support without unnecessary complexity
BitBoxApp integrates directly with portfolio management, updates, and basic security tools without overwhelming the user. Many hardware wallets require extra software — BitBox keeps everything in one place.
Cons & Limitations of BitBox
❌ Limited mobile support
BitBox02 works well on desktop, but mobile support is still restricted. iPhone users in particular will feel limited, which reduces convenience for everyday portfolio management.
❌ Smaller ecosystem compared to Ledger
While BitBox supports major assets, it does not have the same wide coverage, staking integrations, or third party app support that Ledger offers. Some tokens and workflows require extra steps or external tools.
❌ MicroSD backups can cause over confidence
The automatic encrypted backup is convenient, but beginners may forget they still need to store that microSD securely. If the card is lost or damaged without a written seed, recovery becomes harder.
❌ No Bluetooth or cable free mobile connectivity
This improves security, but people who want wireless convenience or mobile friendly usage might see it as a drawback.
❌ Smaller screen compared to competitors
The display is functional but small. Verifying long addresses or detailed transaction data requires a bit more attention than on devices with larger screens.
❌ Far less proven than Ledger or Trezor
BitBox02 is well respected, but it does not have the decade-long track record or global user base that Ledger and Trezor have built. Some investors prefer brands with the longest history in the market.

How to Setup & Use your SafePal
Tangem Hardware Wallet
Tangem is a Swiss fintech company that began its journey in 2017. Headquartered in Zug, Switzerland. Tangem was founded by a small team; including Andrey Kurennykh and Andrew Pantyukhin. Their starting mission was to make crypto self-custody secure, simple, and accessible to everybody.
Early on, Tangem focused on building infrastructure such as smartcard-based hardware and secure chip solutions that could underpin blockchain asset management. Over time, they shifted from B2B supply toward serving retail crypto users directly. This led to the launch of their signature product, the Tangem Wallet, marketed as a card-style hardware wallet, minimalist yet powerful.
What makes Tangem unique is how it blends security and user-friendliness. The Wallet uses a secure embedded chip, evaluated at the high security level EAL6+ ensuring private keys are generated and stored offline, never touching the internet or users’ devices.
Rather than traditional seed-phrase backup systems, Tangem originally embraced a card-based model: each wallet is delivered as a set of multiple identical cards (usually 2 or 3), each able to access the same funds. If one card is lost, the others still work. This design reflects Tangem’s founder belief: self-custody shouldn’t feel complex or fragile.. it should feel as simple as carrying a card in your wallet.
In 2021 Tangem expanded the Wallet to support multiple cryptocurrencies and blockchains. Instead of limiting users to one or two assets, the “multicurrency” version allowed thousands of tokens and numerous chains, giving users flexibility without sacrificing security.
The company’s growth was supported early on by institutional backing. In 2019, they received a USD $15 million investment from SBI Crypto Investment Ltd. (a subsidiary of major financial services firm SBI Holdings), giving them the runway to scale manufacturing, distribution, and product development globally.
Over the years Tangem has expanded its range beyond just cards. In 2024 they launched the Tangem Ring, a wearable wallet device built with the same secure chip and NFC tech as the card. The Ring aims at making crypto self-custody even more accessible and integrated into everyday life, blurring lines between “wallet” and “gadget.”
Despite expansion and technological innovation, Tangem has maintained a strong security profile. Its firmware and chip architecture have been independently audited (by firms like Kudelski Security and Riscure), and as of recent years the company reports zero incidents of wallet hacking or major security breaches.
Today Tangem operates globally, providing hardware wallet solutions in over 170+ countries. Their goal remains the same as day one: bridging the gap between traditional asset ownership and the digital-asset world, making self-custody secure, simple, and accessible.
Models
- Tangem Wallet – 2 Cards Set: Entry version; buy two cards as a set which give you primary + backup.
- Tangem Wallet – 3 Cards Set: Adds an extra card for redundancy (3 cards means one could be lost and still have two left).
- Tangem Ring: A wearable version, a ceramic ring with an embedded secure chip and NFC antenna, designed for everyday carry. It comes bundled with cards for backup.
Feature Highlights
- Card / ring form-factor: No USB cables, no batteries (for the cards), very minimalist and portable.
- NFC Connectivity: The primary device communicates with your smartphone via NFC tap to sign.
- Secure Element & Certification: Chips meet high security standards (EAL6+), designed to resist invasive and non-invasive attacks, including X-rays, electromagnetic pulses, extreme temperatures.
- Smart backup (card sets): Instead of exclusively using a seed phrase, the backup model involves multiple cards which each hold access capability, reducing some user risk of losing seed phrase
- Ease of use: Tangem emphasizes setup in “under 3 minutes”. Designed to be beginner friendly.
- Wide asset support: Thousands of coins/tokens are supported (via mobile app & integrated services).
- Security certifications & audits: Tangem chips are claimed to be certified at CC EAL6+ (a very high security standard), with independent security audits by firms such as Kudelski Security and Riscure
Tangem’s security model stands on several pillars:
- Private key generation & storage: The private key is generated inside the chip of the card/ring and never leaves it. This means extraction of the key is designed to be impossible without physically breaching the secure element.
- Certified secure element (EAL6+): This is among the highest security standards for chips, equivalent in some respects to those used in passports and payment cards.
- Offline / air-gapped nature: Since the cards don’t need to be connected, charged, or plugged in (for many models), they reduce many attack vectors common to USB connected devices.
- Backup via multiple cards instead of seed alone: The multi-card redundancy means losing one card doesn’t immediately result in total loss (depending on config).
- Independent audits & anti-tamper design: The firmware is audited; the hardware is built to resist tampering and environmental damage.
Important caveat: As with all self-custody solutions, user behavior remains critical. Secure backup of your cards, safe storage, avoiding counterfeit cards, & verifying authenticity still are incredibly important.
Pros & Strengths of Tangem
Here are some of the stand-out advantages based on reviews and features:
✅ Uniquely simple & portable form factor (card or ring).
✅ Extremely durable design – resistant to elements, no battery needed for card version.
✅ Beginner friendly: setup is very quick and intuitive.
✅ Very high security certification (EAL6+), independent audits.
✅ Broad asset support (according to manufacturer).
✅ Smart backup model via multiple cards may reduce seed phrase anxiety.
Cons & Limitations of Tangem
❌ Mobile-only interface (at least traditionally): Because the cards rely on NFC and smartphone app, desktop/USB workflows may be limited compared with some hardware wallets.
❌ Slightly less mature ecosystem compared with legacy brands: Some advanced DeFi integrations, desktop wallet support, multi-sig may be less extensive.
❌ Closed-source hardware/firmware: While the chip and firmware are audited, some users prefer fully open-source models for visibility.
❌ If multiple cards are lost or stolen, backup strategy still matters—the user must treat cards like keys.
❌ If you don’t have an NFC-enabled smartphone or prefer USB workflows, the card model may feel restrictive.
Real-World Use Cases & Fit
Tangem is especially suited for:
- Users who want portability and convenience: The card or ring is easy to carry, tap, sign transactions on the go.
- Beginner self-custody adopters: Simple onboarding, minimal cables or fuss.
- Long-term holders and travel-friendly storage: Durable design, multiple cards for backup means you could distribute backup cards in different locations safely.
- Users who want a low-maintenance cold wallet experience: The card model reduces interaction complexity.
It may be less ideal if you are a heavy DeFi/altcoin trader needing wide desktop integrations, or prefer USB/desktop signing workflows or fully open-source hardware.
How to Setup & Use your Tangem
Best Practices for Hardware Wallet Security
- Always buy directly from the manufacturer, never from third-party sellers.
- Initialise your wallet yourself, never use a pre-set seed.
- Keep your recovery phrase offline, stored securely in multiple places.
- Update firmware regularly from official sources.
- Consider multi-sig setups for large holdings.
- Test small transfers before moving large funds.
Now that you have an understanding of each hardware wallet, it’s time for you to make a decision on which wallet best suits your investing goals. After that, select the next lesson that fits your choice.
