In this section, we look at cold wallets, also popularly known as hardware wallets, for the purpose of long-term safe storage of your bitcoin and cryptocurrencies.
In the preceding sections, we have so far tinkered with a hot wallet provided by Blockchain.com on the smartphone and on the web browser. Hot wallets are convenient and allow you access to your bitcoin and other cryptocurrencies on the go on your smartphone. They are generally safe enough for daily spendable amounts.
However, for larger quantity holdings and long-term storage, hardware wallets offer much higher security because:
- Private keys are stored onboard and are never revealed.
- Unlike a data-connected smartphone, they are not connected to the internet by default (hence the term cold) and are not susceptible to phishing and backdoor hacks.
- Spending bitcoin and cryptocurrencies on a hardware wallet requires physical intervention by the user by means of pressing one or two hardware buttons, which means funds cannot be spent remotely unless the wallet is physically present in the hands of the spender.
- PIN on hardware wallets are usually scrambled, so the keying-in of PIN in terms of button presses is different each time and cannot be figured out remotely.
We will cover the three main manufacturers of hardware wallets below. As product updates happen regularly in this niche competitive space, we will cover the features and specifications briefly, and you are advised to check the latest information on these wallets on the official website given in the links below.

For the serious cryptocurrency user and investor, a hardware wallet is not a luxury but a necessity. It is a compulsory instrument to keep your entire holdings secure against hacks and cyberthefts.
You can think of a hardware wallet as a bank vault that you keep safely at home, and your hot wallet or Blockchain app wallet on your smartphone as a wallet on the go. We highly recommend the use of a hardware wallet.
Next in Section 3.1 Where to Buy Bitcoin, we look at the different types of exchanges as well as some safe guidelines before buying our first bitcoin.
