The new Cryptosteel Capsule – it’s sleek, it’s sexy but is it safe?

The Cryptosteel Capsule is the latest storage device to protect your Bitcoin or other cryptocurrency wallet seed phrase. It is sleek, sexy and pretty easy to use. But how safe is it? Let’s take a look at the new capsule style storage device and compare it to the the Billfodl metal storage wallet.

What is the Cryptosteel Capsule?

The Cryptosteel Capsule is a powerful backup solution for preserving critical and sensitive information offline without relying on third parties. You use it to protect and store a passphrase, software generated key, PIN code or other valuable secret.

It’s a sturdy stainless steel capsule-shaped device, intended to endure harsh environments and function under virtually any conditions.

The capsule features engraving, a do-it-yourself assembly process, and a stainless, shockproof, acid-resistant and fireproof material. It is compatible with the majority of secret sharing and key generation algorithms, ensuring that the enclosed data stays safe. Even in cases of aggressive acts such as theft, bribery, vandalism or violence it’s designed to protect the master secret contained inside.

Like other wallets of its kind, it’s stainless steel metal construction is far more durable than paper, wood, and corrosive metals. It is also hard to detect using next-gen methods of surveillance because of the stainless steel metal used.

With Cryptosteel, your most valuable secrets are kept safe both from hackers and from environmental events.

Why do you need one?

Cryptosteel is a physical backup solution for your digital assets and data. Physical storage devices like the cryptosteel are best to keep your sensitive data in an offline environment, safe from cyber criminals and hackers. The durability of a stainless steel construction means that the device will last for years and is impervious to damage and destruction.

The most common use of the Cryptosteel Capsule is to safely store the seed phrase (back up phrase) to your cryptocurrency wallets. Hence the name ‘cryptosteel’. Paper wallets are used for this purpose today, but can be easily destroyed, lost or stolen. Even if you use a hardware wallet, you should still have a Cryptosteel as a backup in case of loss or damage to your hardware wallet or compromise of your private keys.

A metal storage solution for your seed phrase means that you can recover your cryptocurrency as a last resort should anything go wrong with your digital wallets.

The Cryptosteel Capsule is an excellent choice to store your cryptocurrency seed phrase because:

  • it is made of a sturdy, shockproof and acid-resistant material
  • the assembly is do-it-yourself, so you can be sure that the encryption process is done properly, by you!
  • it features a variety of compatibility with secret sharing and key generation algorithms, including the BIP39 standard for mnemonic seed phrases commonly used to recover lost cryptocurrency.
  • it is fireproof and waterproof.
  • its stainless steel construction means it can’t be detected by high tech scanners.
  • it can function under virtually any conditions.

For more than just your crypto seed phrase

Cryptosteel Capsule can also be used to protect other types of secrets or keys such as:

  • BIP39 (unabbreviated 12-word recovery seeds),
  • Shamir Backup SLIP0039 (4-letter abbreviations of 20-word recovery seeds)
  • BIP32 root keys
  • WIF private keys
  • Monero mnemonic seeds (25-word recovery seeds)
  • Random ASCII passwords
  • PINs
  • Insurance account numbers
  • Master passwords to your password manager (e.g. LastPass, KeePass, 1Password)
  • Bank account info and passwords
  • GPS coordinates
  • Poems and haiku
  • Rainbow Codes
  • Elliptic curve coordinates.

How is the Cryptosteel Capsule different from other metal storage wallets?

The Cryptosteel is also unique in that it allows you to use a variety of secret sharing and key generation algorithms. This provides extra security for your data. The Billfodl and other similar metal wallets only support the BIP39 standard for mnemonic seed phrases. While you might buy the Cryptosteel Capsule for your cryptocurrency, you can use it to store a range of other secrets.

The design of the Cryptosteel Capsule is also different. It’s a cylindrical shaped device containing a stainless steel rod on which you arrange the engraved tiles into words, numbers or phrases that form your secret. The tiles are kept in place with a fastener and there are spacers that you can use to break up words. The tiles contained within the cylinder are obscured from view by the stainless steel capsule and cap. The device measures around 10cm in length and 1.6cm in diameter. It is slender and therefore easy to conceal somewhere or to hide.

Most other metal storage wallets are shaped like a cassette or credit card holder. They’re flat with a stainless steel sleeve and a chassis with your tiles hidden in between.

Is the Cryptosteel Capsule safe?

The answer is yes, the Cryptosteel Capsule is safe. It’s safe from damage, destruction, prying eyes and of course from cyber attack. But not as inherently safe as the Billfodl metal storage wallet in our view. This is because the device itself doesn’t lock. A cap screws on to the capsule and can be fitted with tamperproof seals. While you will (eventually) know if someone finds your Cryptosteel Capsule (because the seal is broken), that person will also have almost immediate access to the inside of the device, and your secret phrase. They could access your seed phrase and write it down easily, with no deterrent except a seal sticker to overcome.

The BillFodl on the other hand has separate locking protection on the outside of the chassis, where you can fit your own padlock. While padlocks can be broken, this does add an extra layer of protection on top of the Cryptosteel. If someone finds your device, they can not get into it as quickly or easily. And this may just be enough to deter their curiosity, so that they move on to something else. If you want the BillFodl to remain undetectable to scanners, you simply need to buy a stainless steel padlock to use with it.

Billfodl with padlock protection

Like any metal storage wallet, the Cryptosteel Capsule itself can still be stolen. So you need to keep it in a safe place. The good thing about the capsule design is that there are no hinges, pins or moving parts. You can bury it, or hide it inside a wall and still retrieve your tiles from inside of the capsule without worrying about dirt jamming up the device.


The Cryptosteel is a nice addition to your crypto security arsenal. It’s also more flexible than other wallets in that it can be used to protect lots of different types of secrets or keys. It’s the slickest, sexiest looking metal storage wallet on the market! But if you’re strictly buying a metal storage wallet to protect your crypto seed phrase, then we prefer the BillFodl for that extra level of security that acts as a deterrent from prying eyes.

You can buy the Cryptosteel capsule directly from the Ledger website here. The device will cost you a little more than the Billfodl will.

The Billfodl is available for purchase direct from the manufacturers Privacy Pros.

The safest and best wallet for Ethereum: everything you need to know

wallet for ethereum

There are over 50 different wallet for Ethereum token as we write. Now we’re pretty sure you don’t want to go through the pros and cons of that many wallets to work out which one is the best wallet is for you. So that’s the question we will answer in this post!

To find the best wallet for Ethereum, we have to make some assumptions about what you, our readers, wants to do with your ETH tokens. So, we will assume that like most crypto users, you want to hodl some Ethereum as well as use the Ethereum ecosystem to access DeFi, blockchain gaming, and NFTs.

Before we launch into our Top 4 wallet picks, let’s first start with a quick look at what the Ethereum token is.

What is Ethereum (ETH)?

Ethereum (ETH) is a cryptocurrency and the native token to the Ethereum Mainnet. Ethereum Mainnet is the dominant layer 1 smart contract blockchain in the cryptocurrency world, and has been since crypto first began.

Ethereum Mainnet is smart contract blockchain technology

The Ethereum ecosystem comprises all of the layers of software products and services built on the Ethereum blockchain. The native Ethereum ecosystem is the most extensive ecosystem in cryptocurrency. Hundreds of different decentralised apps, Decentralised Finance protocols, crypto exchanges, gaming applications and NFT marketplaces are built on top of the Ethereum blockchain. You can explore the dApps built on the Ethereum Mainnet here.

Whenever these applications are used, the ETH token is required to pay ‘gas fees’ to use the Ethereum blockchain. ETH token is also used as native currency for some decentralised applications and protocols built on Ethereum. For example, many popular NFTs minted on the Ethereum Mainnet are priced in ETH.

The ETH token is multifunctional – ETH is ‘gas’ for the network, it’s a native currency, and it’s also a digital asset store of value for many crypto investors. This is important to understand because how you use ETH can impact the type of ETH wallet that best suits you.

What is an Ethereum wallet?

An Ethereum wallet stores the private keys to your ETH tokens. When you want to transact your ETH tokens, you use these private keys to sign the transaction. Blockchain transactions are cryptographically secured with private keys. Your private key ensures that only you have access to the tokens you are transacting, so that nobody can take your crypto from you without having your password or authorization.

Different types of Ethereum wallets

An Ethereum wallet can take different forms. For example you can have:

A cold storage Ethereum wallet that stores your private keys completely offline and never exposes them to the internet. This is the safest type of wallet for Ethereum as cyber criminals are unable to get access to your offline wallet to steal your private keys and crypto.

A hot wallet for Ethereum which is connected to the internet. A hot wallet is typically a mobile phone app, browser extension, or website. Because it is connected to the internet, it’s not as safe a cold storage Ethereum wallet. A hot wallet secures your private keys online using password security, 2FA and other similar means. Like anything with password protection, hot wallets can be cyber hacked and your private keys (and cryptocurrencies) stolen. There are ways to make your hot wallets more secure, but they generally involve connect and protecting them with cold storage security. We’ll go into this more below.

What to look for in a wallet for Ethereum?

The top features you should look for in an Ethereum wallet include:

  1. Functionality – we’ve chosen wallets for Ethereum that you can use across the Ethereum ecosystem for DeFI, gaming AND NFTs.
  2. Security – the best wallet for Ethereum should integrate with a hardware wallet, so you can make sure you keep your private keys offline at all times. This is the ONLY safe way to protect your crypto assets from hackers.
  3. Portability – a good wallet for Ethereum should have both a mobile and web versions. A web version is important if you want to create and mint your own NFTs. A mobile version is critical to almost everything else.
  4. Smooth on-ramp – we include only those wallets that allow you to buy ETH with a bank card or VISA.
  5. Easy importing to other clients – the wallet needs to be partnered with lots of other crypto projects so its usable across the Ethereum ecosystem.

The best wallet for Ethereum – our Top 4

We’ve left the best til last! Based on these features, here is our list of the top 4 wallets for Ethereum:

1.Ledger and Trezor cold storage wallets

Ledger and Trezor are cold storage wallets. For all you need to know about cold storage wallets, check out our recent post here.

Functionality – Both Ledger and Trezor wallets support ERC20 (ETH and Ethereum based tokens) as well as NFT files.

Security – Ledger and Trezor are listed together because they are the best hardware wallets on the market from our extensive hardware wallet reviews. These hardware wallets are the most secure way to store or hodl your ETH. They are a MUST if you want the best protection for your crypto.

Portability – Ledger has an accompany Ledger Live (mobile and desktop) App. Ledger also supports WalletConnect. Trezor comes with Trezor Suite Desktop App (no mobile wallet version).

Smooth on-ramp – You can buy ETH and other crypto directly in the Ledger Live App (which you download and use with the hardware device). You’ll pay fees to these banking service providers, which are Wyre and Coinfy. Trezor wallet also lets you buy ETH through a selection of 9 different crypto exchanges or direct SEPA transaction.

Easy importing – Since both devices connect to MetaMask, you can virtually connect to any dApp or protocol in the Ethereum ecosystem with hardware level security.

The rest of the wallets on this list are hot wallets, which means they store your private keys on your mobile phone or laptop. While your private keys are protected by wallet security when online, they are still susceptible to hack. This is why we have prioritised hot wallets that connect with either Ledger, Trezor or both. We highly recommend using this combination when hodling and using your ETH, to get the flexibility and functionality of a hot wallet with the security of cold storage.


Functionality – One of the original wallets for Ethereum and also one of the most trusted, you can use MyEtherWallet for the big 3 – DeFI, gaming and NFTs.

Security – MyEtherWallet connects with Ledger Nano and Trezor hardware wallets, to provide hardware level protection for your ETH and NFTs.

Portability – MyEtherWallet is available in app form and as a web wallet.

Smooth on-ramp – You can by ETH via simplex using your VISA or MasterCard. If you’re European, you can also cash out to Fiat currency through partner Bity.

Easy importing to other clients – MyEtherWallet connects seamlessly to exchanges and DeFi protocols through WalletConnect and WalletLink.

3.MetaMask wallet

FunctionalityMetaMask is the ubiquitous ETH wallet – used for DeFI, gaming and NFTs. MetaMask does not offer a lot of native functionality in the wallet itself. However, it connects to almost every Ethereum platform, dApp and protocol out there, so you don’t really need the wallet to do much.

Security – You can use Ledger or Trezor hardware wallets to secure your MetaMask with cold storage protection for your private keys. We don’t recommend leaving your crypto on MetaMask without a hardware wallet connected however. Just too many hacks of the hot wallet version…

Portability – MetaMask comes as a browser extension and mobile app. Both sync pretty seamlessly.

Smooth on-ramp – You can buy ETH directly in-wallet through either Apple Pay, bank transfer or credit card. Metamask takes a fee itself in these transactions and you will pay a fee to Apple or Transak (for bank transactions). You also pay the gas fee to use the Ethereum network. It’s not the cheapest way to get your ETH.

Easy importing to other clients – We haven’t found a platform or application it won’t connect to in the enormous Ethereum ecosystem

4.Guarda wallet

Functionality Guarda Wallet offers NFT storage as native and integrated DeFi capabilities. You can also manage your blockchain or .ENS domains using Guarda wallet. This is functionality Metamask doesn’t offer yet. For ETH hodlers, Guarda runs it’s own staking pool for ETH. This means you can stake your ETH in the Guarda app and earn 14.5%. Guarda supports over 50 different blockchains and hundreds of coins and tokens. There’s a coin search function here if you want to make sure your coins are supported.

SecurityGuarda Wallet lets you connect a Ledger device to their platform, so you can securely display your balances and manage your transactions.

Portability – The Guarda Wallet comes in mobile, desktop and web versions.

Smooth on-ramp – You can buy 300+ different coins and tokens, including ETH, directly in-wallet using VISA or MasterCard.

Easy importing to other clients – You can easily connect Guarda Wallet to various DeFI protocols with the WalletConnect integration.

Conclusion – which is the best wallet for Ethereum?

All of the wallets on this list will let you navigate the Ethereum ecosystem securely and access Ethereum’s its DeFi, NFT and gaming benefits. However, the combination of Guarda wallet + Ledger is overall the best wallet for Ethereum based on our research. This combination is easy to use, you can keep your private keys securely offline and best of all, you can stake your ETH inside the app and earn rewards while you hodl! (Note, all staked ETH is locked until the release of ETH2.0).

Getting started with cold storage wallets: all you need to know

Cold storage wallets

The safest way to store your cryptocurrency is in a cold storage wallet. Cold storage wallets come by many names and have been around since crypto began. They are a secure type of storage for your cryptocurrency private keys that is not connected to the internet. You can either create a cold storage wallet on your own or buy a device that will store your private keys for you. In this blog post, we discuss different cold storage wallets, why you need them, and the three leading choices on the market today!

What are cold storage wallets?

Cold storage wallets are just a secure place to store the private keys to your cryptocurrency offline – not connected to the internet.

Your private keys give you access to your cryptocurrency on the blockchain. You need your private key any time you want to complete a crypto transaction (sell, send, stake it etc). Your private key is used to digitally sign your transaction. This means that if someone else has access to your private keys, then they can easily steal your cryptocurrency. They would do this by using your private keys to approve a transaction that sends your cryptocurrency to a different public address.

Cold wallets keep your private keys in an offline environment. They also let you sign any transactions in that same offline environment so that your private keys are never exposed to the internet.

Keeping your cryptocurrency in cold storage – not connected to the internet – is the best way to keep it safe from being hacked and stolen. Hacking and theft of cryptocurrency is one of the biggest risks to the security of your crypto today.

Different types of cold storage wallets

You can store your crypto in cold storage via a few different means:

  1. Paper wallets
  2. Crypto software wallets (in offline mode)
  3. Hardware wallets

Let’s take a look at each…

Paper wallets

This is where you print out your public address for a particular cryptocurrency (for example Bitcoin) as well as the private keys for it. You then store the print out in a safe place offline – like in a safety deposit box or other secure location.

if you want to go down this route, you can use this site – – to generate your paper wallet.

Before you use this private key generator tool, make sure you are in a secure operating environment (someone could be looking at your screen). Using something like Unbuntu might be the way to go. You should also make sure that your printer is offline. It’s a good idea to test everything before you go ahead and generate your private key.

Because it’s tricky to get right, this method of cold storage is not popular. We don’t recommend paper wallets as you need to be somewhat tech savvy to generate them securely. If anything happens to the paper your private keys are printed on, it would be hard for you to recover the crypto stored on it. It’s also not user friendly and not very accessible.

Crypto software wallet (offline)

You can also store cryptocurrency in cold storage using an offline version of the crypto software wallet. A software wallet is also called a desktop wallet. You can download these wallets offline and store them securely on your computer until you need to access them again. They are user friendly but not as convenient as hardware wallets. This is because many can’t to connect with other devices like smartphones, tablets etc.

Armory is a popular desktop wallet. It’s regarded as the most stable and secure because private keys are kept in an offline computer and only the person with access to the physical location of your machine can steal your crypto. Users have total control over their secret key.

Another popular desktop wallet is Exodus. These software wallets allow you to store your crypto in ‘offline mode’ but you can’t transact with them when offline.

Crypto hardware wallet

You can also store your cryptocurrency in cold storage using a crypto hardware wallet. A hardware wallet is a small USB sized device that stores your private keys and lets you send and receive crypto. The main benefit of a hardware wallet is that it’s much easier to use than paper wallets – all you do is plug in the hardware, create a pin number, make sure you have your recovery phrase stored somewhere and go!

A crypto hardware wallet is definitely the best way to go if you are looking for cold storage. This is because hardware wallets offer the best offline security. They also offer increasing convenience to transact your crypto and interact with third parties like DeFi protocols in a secure way.

If you’re looking for a hardware wallet it can be difficult to tell the difference between top brands on the market. You’re going to need to know which has the best security features, which to use with your mobile phone or desktop computer, and which coins each device supports. That’s why we’ve done the research and ratings for you, right here!

In the meantime, let’s look at the top three cold storage wallets on the market.

Top three cold storage wallets

Ledger Nano X

Ledger Nano X is one of the most popular hardware wallet on the market and our pick for top cold storage wallet.

cold storage wallets
Ledger Nano X – best cold storage on the market

The Nano X is super easy to use and has many customizable features that make it user friendly for anyone. This device can store 100 different cryptocurrencies at once and supports a list of up to 1800 coins and tokens.

You also have peace of mind when you buy the device that you are receiving the real deal in the mail because Ledger offers a software device validation check when you’re setting it up. No other hardware wallet that we know offers this. Ledger also has a great native app – Ledger Live that allows you to monitor, manage and transact your crypto in tonnes of different ways. You can also connect to third party providers for more options.

Trezor Model T

Trezor Model T is the gold standard cold storage device from Trezor and another popular hardware wallet. It offers two factor authentication features that are not available with the Ledger hardware wallets. It’s also one of the best cold storage wallets for security and has a user friendly interface that makes it easy to use for anyone looking for an offline crypto solution.

Ledger vs Trezor
Trezor Model T our of the box – great cyber security and extra 2FA.

Trezor doesn’t have the full featured app that Ledger Nano X has. To try to overcome this, Trezor has teamed up with software wallet provider Exodus. If you use both together you can get the security of a hardware wallet with the simplicity and user-friendly design of a software wallet (Exodus). You can use a Trezor to overcome all software wallets’ security problems while Exodus gives you the nice user experience while managing your crypto assets.

Ledger Nano S

Ledger Nano S our third ranked hardware wallet, and best budget option. Ledger, the makers of the Nano S claim it is the most sold hardware wallet in the world! This cold storage device has a sleek user interface and is one of the best ways to keep your cryptocurrency safe from being hacked for around half the price of the Nano X.

cold storage wallets

So how does the Nano S compare to the Nano X from Ledger? For one, it’s cheaper. This is because there are some trade-offs compared to the premium Nano X wallet. Firstly, the Ledger Nano S only connects to your phone via cable. The Nano X on the other hand has both Bluetooth and cable connectivity. Secondly, Ledger Nano S supports the same diversity of coins as the Nano X, but you can only store up to 6 at once. This is why it’s the budget option. Lastly, the Nano S doesn’t have Bluetooth connectivity like the Nano X.

If you just have some Bitcoin and want somewhere safe to hold it, the Nano S is a top choice cold storage wallet. Check out our choice for best ‘Bitcoin only’ wallet here.

It’s important to find the best hardware wallet for the way you use cryptocurrency. You don’t want to pay for bells and whistles you don’t use! To find the best wallet for you, check out our full review of each of these wallets here. We review the pros, cons, pricing and features that differentiate each wallet.

The importance of diversifying your crypto storage

The thing about cryptocurrency is that you are your own bank. You need to make sure you have the best security in place for your investments. If anything does happen, such as hack or theft of your hardware wallet, it’s best to make sure you don’t lose everything. The solution is to diversify your asset storage across different cold storage wallets. Use multiple hardware wallets and store them in different locations.

Why cold storage wallets are not the only security you need

Cold storage wallets are not the only security you need for your crypto assets. You should also make sure you have a metal storage wallet for each hardware device you own. A metal storage wallet is where you store your 12 word recovery phrase for your Bitcoin or Ethereum.

We recommend the Billfodl metal storage wallet to securely store you recovery phrase. If you want to see our complete Billfodl review, check it out here. Once you have your metal storage wallet set up, make sure you keep it in a separate location to your hardware wallet.

Your metal storage wallet is your last line of defence. With a metal storage wallet, you can always recover your crypto should anything go wrong with your cold storage wallets.
