How to Store Bitcoin Offline in Cold Storage in 2021

Bitcoin’s streak of breaking its own record price has been relentless for the past few months, with the cryptocurrency climbing over $14,000 (about Rs. 9 lakh) this week, from having been less than $800 (about Rs. 51,600) this time last year. This unprecedented growth – nearly 10 times its value since the start of 2017 – has brought Bitcoin squarely into mainstream attention.

Though the debates over the currency being in a bubble continue to have voices from all directions, what’s clear is that those with a big stake in Bitcoin need to be safer than ever with their digital investment. After all, it’s real money that’s at stake. Bitcoin wallets have faced multiple hacks in the past, so it’s worth going the extra step to secure your funds.



The most convenient way to store Bitcoins is by using an online wallet, which allows you to quickly transfer money in and out of the wallet or turn Bitcoins into alternative cryptocurrencies such as Ethereum, Monero, Litecoin, and others. But the safest option is known as ‘cold storage’, which stores your Bitcoins offline away from any Internet access. This is all the more important if you’ve got large amounts of Bitcoin.

Here’s how to set up cold storage for your Bitcoin wallet:

1. Paper Wallet

The easiest way to take your Bitcoins offline is by using paper and a printer. Yes, really. You’ll also need a website that allows you to create an offline Bitcoin address, such as Bitcoin.com or Bitaddress.org. Follow these steps to create a Bitcoin paper wallet:

  1. Head to the Bitcoin.com Paper Wallet or the Bitaddress.org page.
  2. Save the page locally to your computer as an HTML file.
  3. Next, close the page and disconnect your computer from the Internet.
  4. Open up the saved local version of Bitcoin.com paper wallet or Bitaddress.org.
  5. Follow the instructions on the page to create a new Bitcoin address.
  6. Once you have a pair of keys and QR codes, print the page. Make sure your printer is not connected to the Internet for added security.
  7. You can now use the new public address/ QR code to transfer Bitcoins from another online wallet.

The printed page is the most valuable piece of document for your Bitcoin investment. You should ideally store the printed page in a water and fire-proof container, such as a safe. If that’s not an option, create multiple versions of it and give it for safekeeping with trusted family, in the case of damage to your version. You could also laminate the page for protection.



2. BitKey

While taking your computer and printer offline is a good security measure, it’s not as safe as using a clean operating system. BitKey is basically a free bootable Linux distro that you can write to a USB drive or CD-ROM. Plus, it can run live from the computer’s memory (RAM) so you can eject the drive/ disc once it’s running.

BitKey comes pre-installed with multiple software options: Electrum Bitcoin client, WarpWallet (more on that later), and Bitcoin paper wallet among others. It also has a built-in network, printer, and wireless managers so you can use it for all necessary Bitcoin purposes. Creating a paper wallet with BitKey is safer than using your existing OS.

  1. Here’s how to create a bootable USB/CD with BitKey:
  2. Head to the BitKey website to download the OS image.
  3. Click the Download button, and get the 64-bit version.
  4. Choose between USB and CD-ROM. The latter is safer since they are read-only by default. For USB sticks without write protection, it’s advisable to remove them after boot.
  5. Burn a CD with your favorite program, or use a utility such as UNetbootin to write the BitKey ISO to a USB drive.
  6. Boot into BitKey by using your computer’s advanced boot function (varies from F8-F12 depending on motherboard manufacturers).

If the boot is successful, you can use BitKey to create a paper wallet, and you can even use the Electrum client to create an offline wallet. BitKey provides three operation modes – cold-offlinecold-online, and hot-online – which define whether the computer is offline and air-gapped.

It also decides how convenient the process will be. Choose cold-offline in BitKey for maximum security and least convenience, and hot-online for lesser security and more convenience. You can only prepare transactions in cold-online, though. Follow the three links to figure out which method works for you best.

3. WarpWallet

The even more paranoid, and even safer way to store Bitcoin involves something called a brain wallet, which generates an address by using a memorized passphrase. WarpWallet takes that a step further with “salt”, an additional piece of data such as your email address which forces attackers to target you individually instead of casting a wide net.



This way, your private key isn’t actually stored anywhere physically or digitally, it’s in your head (read: brain). That means you don’t have to take care of a piece of document, as long as you don’t forget the passphrase, for which most people advise that you leave cryptic notes around the house.

Owing to the complexity and secure nature of this method, it’s been described as how Jason Bourne stores his Bitcoin. Anyway, if you think this is the way to go, here’s how to get started on WarpWallet:

  1. Head over to the WarpWallet website, and make note of the SHA-256 sum in the URL.
  2. Save the page locally to your computer as an HTML file, and transfer it to a USB drive.
  3. Boot up a bootable Linux distro, such as BitKey from above.
  4. Copy the HTML file over to BitKey.
  5. Open sha256sum warp.html to verify the SHA-256 sum matches the one from step 1.
  6. Open the HTML file as a local file in Chrome/Firefox.
  7. Generate a passphrase that works on an entropy algorithm, such as One Shall Pass. Anything with 58 bits or more of entropy is very secure.
  8. Use the passphrase in the HTML file, and your email address as “salt”.
  9. Scan public key QR code with the phone, and transfer it to a device with the Internet.
  10. Shut down BitKey.



You can now transfer Bitcoin from your online wallet/ exchange to your WarpWallet address. You don’t have to store your private key anywhere, as it can be regenerated with WarpWallet’s website, with the help of your passphrase and “salt”. Just don’t forget any of the details, or your Bitcoin (and the money invested in them) are gone forever.

These are the most popular ways to store Bitcoin offline. If you want something with more convenience than BitKey and WarpWallet and are willing to spend for it, look at hardware wallet options such as TREZOR. They cost a lot – TREZOR comes in at over Rs. 8,500 including shipping to India – but they are easier to use than booting a Linux distro.

WhatsApp Pay

UPI apps are consistently getting new users in the Indian market with the boom in digitization all across. WhatsApp which is a popular instant messaging platform also joined this race recently in the country. WhatsApp Pay finally arrived in the Indian market this month after years of anticipation.

It comes as a rival to the existing players such as Google Pay, PhonePe, and Paytm in India. We have shared the steps to send money via WhatsApp Pay. You can send money both via UPI ID and QR codes using this digital payment option.

Since WhatsApp is one of the most secure messaging platforms, the company has made sure the new feature is also safe from external threats. To complete any payment, you will need to enter the security pin or OTP’s. But, this doesn’t mean it is completely protected from thefts and other security issues.



We know how scamsters all across take advantage of the loopholes and steal your hard-earned money. There have been incidents of fraud on other UPI apps as well in the past. So, what can you do to stay safe from any scam or fraud on WhatsApp Pay? This article will guide you with the same. Take a look:

How To Stay Safe From Frauds And Scams On WhatsApp Pay

Fraudsters generally would disguise themselves as some high-ranking officials when they contact you. You need to be aware and analyze the situation. If an unknown person sends you a text message or calls you claiming to be one such professional or a relative and ask for money, do not hesitate to say no to give out any financial details.



Specifically, if you are being sent any suspicious links, don’t click on them. These links contain malware that can help the attackers steal your data. Another scenario includes these fraudsters sending you an unauthorized payment request. Do not approve as this could deduct the money from your account itself. Hence, make sure you accept such requests from trusted sources only.

Sometimes, the person doing a scam would act as a bank official and ask for your banking details. You should be aware that no bank would ask for personal banking details, so never share such information. Specifically, OTP’s for payment completion. Be aware of the frauds where you will be lured to withdraw some kind of prize money or lucky draw. That’s a way to clean all the nickels out of your e-wallet.
