How Can You Improve the Security of Your Crypto?

It’s true that when storing and using cryptos like Bitcoin, there are threats you don’t have to worry about when compared to traditional currencies like dollars.

Since you must custody your own money when using crypto, it’s important you store it correctly.

And that means a good back up of your wallet is necessary.

That’s why steel wallets have now become a big trend when it comes to securing your coins.

Key Takeaways

  • Your wallet seed words allow you to recover your Bitcoins. It's critical to have a secure backup like a steel wallet.
  • Steel wallets will protect your wallet seed from: corrosion, fire, hackers, rust, water and more.
  • Steel wallets cost between $30 to $120. More money will get you more security.

What Is a Cryptocurrency Steel Wallet?

Hardware wallets like the Ledger Nano X and Trezor T are popular because they offer a much more secure way to store your Bitcoins or Ethereum than the software wallets you get from crypto-exchanges, like a Coinbase wallet.

The downside of hardware wallets is that you can lose all your Bitcoins if you accidentally break or misplace your Bitcoin wallet – or it gets stolen.

That’s where the seed phrase comes in.

24 word seed
What a mnemonic seed phrase looks like.

It’s a combination of random words that enable you to access your Bitcoins on the blockchain in case you lose access to your hardware wallet.

But private keys and seed phrases can also be a major security risk.

Enter the cryptocurrency steel wallet.

A metal wallet is another cold storage wallet that securely backs up the recovery phrase (another word for private keys and seed phrases) to your other hardware wallets so you never lose access to your Bitcoins.

Why People Need Steel Backups for Wallet Seed Storage

You could just write down your private key or seed phrase on a piece of paper and store it in a safe place. But that makes it no more secure than a paper wallet – and that’s risky business.

Most steel wallets, on the other hand, are corrosion resistant to pretty much any physical threat or natural disaster.

Steel wallets protect you from fires, floods, and even nuclear fallout.

Some examples threats steel wallets protect your seed from include:

That makes steel wallets almost indestructible. Some manufacturers even go so far as to make videos where they try (and fail) to break them.

Now that you know how steel wallets work and why they’re important, it’s time to look at some of the best-selling steel wallets on the market right now.

The 5 Best Cryptocurrency Steel Wallets

BillfodlBillfodl Backup Read Review

Privacy Pro's Billfodl is made from stainless steel (grade 316), which makes it a very tough wallet that is particularly corrosion resistant. At $99, it is a great choice for the hodler who wants value for money without compromising on quality. And best of all, they are the only backup that offers a 125% money back guarantee for life (yes, they pay you if you don't like it)!

  • Simple setup process
  • Compatible with all crypto wallets
  • Scientifically tested at a Dept. of Defense ordinance testing facility
  • Very strong and competitively priced
  • You may need to pre-order to get one since so many people order them.

billfodl logo whiteBillfodl Multishard

The Billfodl Multishard is Billfodl's upgraded solution to backing up a seed phrase. Other backups do not protect against someone finding the backup and stealing your coins. The Multishard solves this problem by providing an easy way to distribute your seed phrase into parts so that you need at least 2 of the 3 pieces to gain access to your coins.

  • 2-of-3 style backup
  • Finding one does not mean you lose your coins
  • Same quality and 125% money back guarantee as the Billfodl
  • Takes longer to set up
  • More expensive that other options
  • More advanced option

Cryptosteel Capsule

This second generation backup from Cryptosteel is made from stainless steel (grade 304). It sells for $99 on Ledger's store, making it slightly more expensive than the cassette. It features a tube shape where tiles are dropped onto a core held within the tube. The idea is that metal bending is less likely in a house fire and so the structure of the tube should be more robust.

  • Very reasonably priced
  • Beautiful packaging makes it easy to change seed
  • Easier to load than a cassette style backup
  • Not very easy to recover wallet from
  • Easier to lose the seed when recovering

Cryptosteel Cassette

The original stainless steel backup, Cryptosteel is made from stainless steel (grade 304). It sells for $90, so it quite a bit more expensive than the alternatives. They also sell another version called the Capsule for $163 that uses a slightly different backup method.

  • Tiles are not consistent, which makes them difficult to insert
  • Better options at the same price point
  • Bad support


CRYPTOTAG is a titanium wallet that differs from Privacy Pro's Billfodl and Cryptosteel in that the user must use a hammer or engraving pen to stamp or engrave his own letters into the metal plate. It comes in two versions, the Thor ($199) and the Zeus ($109). Because the Thor comes with a hammer, 26 letter bits, a bit holder, two stainless steel plates, earplugs, matches, and an anvil in the package, it is the more expensive set.

  • Allows for up to 48 words
  • Extremely high melting point
  • Includes all necessary tools
  • Tamper-resistant
  • Requires hammer and stamping kit to record seed phrases
  • Not re-usable
  • Risk of Injury during set-up

What are the Cons of a Steel Backup?

It’s important to remember that anyone who finds your steel backup would have access to your coins. After all, the whole point of the steel wallet is to backup a recovery seed which you use to get your bitcoins and altcoins back if you lose your wallet or it is destroyed.

Therefore, you need to make sure that your steel wallet is always somewhere no one else would find it. At the very least, make sure it is somewhere that only people you trust could find it. You may even want to instruct your spouse or significant others that they can use this device to access your funds in the case of your death.

The point is, steel wallets are meant to protect your Bitcoin seed phrase from destruction by fire and water damage.

How do I back up a Multisig?

If you have a multisig wallet, you will have several recovery seeds. One of these devices will, therefore, not be enough to backup all of the recovery seeds. You will need to buy one device for each recovery seed you have. So for instance, if you have a 2-of-3 multisig, you will need to buy three of these backup devices.


Do not store all three of your backups in the same place. This eliminates much of the protection that a multisig gives you since anyone who finds one of your recovery seeds has found all of them. They will then be able to recover all of your signatures and take your coins.

Billfodl Multishard

The Billfodl Multishard allows you to split your recovery phrase into a 2-of-3 backup.

Here’s how it works:

The Multishard comes with three separate units, each labeled to include 16 of the 24 words.

The Billfodl Multishard

This means that to recover your coins, you would need any two of the three backups.

This protects your coins in case someone finds a Billfodl because they won’t have the entire seed phrase.

This also protects from major damage, such as being lost in the rubble of a collapsed apartment building.

The idea is to put each of the units into different places so you have redundancy.

Which one will you choose?

As you can see from our comprehensive review, steel wallets serve an important function when it comes to protecting your Bitcoin or Ethereum.

Just to recap what we’ve covered in this guide:

Hopefully, you’ve found a steel wallet that suits your requirements and budget. But watch this space – more manufacturers will no doubt enter the market in the coming years.

Cryptosteel Review

Cryptosteel vs Other Steel Wallets

The Basic Cryptosteel

The Basic Cryptosteel (starts at $79): This is the company’s best selling item. It can hold 24 four-digit mnemonics total, in addition to over 245 uppercase letter tiles.

cryptosteel original

It also comes with blank tiles to facilitate 3-letter mnemonic words. At 455 grams, the wallet is quite easy to carry.

Cryptosteel Capsule

Cryptosteel Capsule is a hollow cylindrical tube with a column in the middle.

Like the original cryptosteel, you are given stainless steel donut-shaped tiles with letters stamped on them.

cryptosteel capsule

The tiles are stacked, one on top of the other, by dropping them onto the column in the center of the tube in the order that spells out your seed.

The idea behind this design is to make the process of seed storage cheaper and easier to set up, but with the draw back that it’s easier to make a mistake.

One of the main benefits is that the letters of each word are not displayed directly. You have to open the capsule to see the words, making the Capsule slightly more discreet than the original Cryptosteel.

What Kind of Protection Does Cryptosteel Offer?

The standard option comes with a total of 24 slots. Each slot is able to hold 4 letters – this is all you need to recover the entire word from the BIP39 word list of 2,048 possible options.

I did not personally run stress tests, but I did see some YouTube videos that show the wallet being tested. It can bear extreme temperatures and will not sustain damage be it fire or water. In fact, it is fireproof up to 1200°C. Moreover, it comes with a unique Lifetime Satisfaction Guarantee.

This was enough to convince me about the quality of the product. It feels sturdy in hand and I also liked the feel. It’s as big as a credit card but much heavier.

The level of protection is excellent. It doesn’t matter what the wallet has to go through, the letters will still be readable.

While cold-storage wallets offer security against hackers, theft is still a possibility.

In case you lose your wallet, you should first generate a new seed. Plus, if you have Trezor or other such devices, you can add another layer of security by applying an additional password. Moreover, there is also the option to use a padlock to deter thieves. It can be bought separately.

Do You Need Cryptosteel?

Online security is a major concern. Most users are afraid of storing their private information on the web. It may be a good idea to invest in Cryptosteel if you have made a large investment in digital coins.

Since it is made of stainless steel, it can go undetected. You will have no difficulty in storing it, which is a great plus. Additionally, the company offers free international shipping ($150 or bigger orders).

It also offers more security than writing down your mnemonic code on a piece of paper. Plus, it’s compatible with Trezor, Ledger Nano S, and KeepKey.

It might be a little on the expensive side, but it’s worth the price considering you will not have to replace it anytime soon due to it being very durable and long-lasting. Plus, there is no risk of a security breach since the entire process is offline.

Packaging and Handling

I was quite impressed when I first got my hands on the device. It looks quite neat and is easy to hold. However, remember to be careful when opening the package as it contains small items. You don’t want to lose anything.

The artwork is quite impressive as well. It gives the device a unique appearance.

Unfortunately the packaging leaves A LOT to be desired. The tile tray leaves the tiles in a giant mess which means setting it up can take hours as opposed to Billfodl which only takes a few minutes.

Cryptosteel – Disadvantages

It can be difficult to store and sort out the tiles. Plus, you cannot use it to store BTC addresses or other such information as it does not come with numeric tiles. Again, something that Billfodl includes in their basic product.

Also, some users complain about a lack of uniformity when it comes to tiles. I did not face such problems personally. If this is the case, you will have to manually polish the tiles to ensure they fit well.

Having used and reviewed Cryptosteel, I can say it delivers what it promises. If you have invested big in cryptos, then it may be a good option to buy this wallet.

Can you use Cryptosteel with Ledger and TREZOR

Yes, Cryptosteel is compatible with the Ledger Nano S, Ledger Nano X, and both TREZOR models.

Cryptosteel vs Billfodl


There are two main differences between the Billfodl (read our Billfodl review) and Cryptosteel.

The Billfodl is cheaper and comes with faster shipping.

Billfodl’s built with Marine-Grade 316 Stainless Steel, while Cryptosteel is built with basic 304 construction steel.

Billfodl also offers a 125% money back guarantee for life if you don’t like it and, as mentioned previously, has a much better tile organization.
