BitBox promo code MADTRADES applies a 5% discount to BitBox hardware wallets bought from the official Shift Crypto shop. This guide explains what the device does, how the two current models differ, when the Bitcoin-only edition is the better choice, and the security rules that matter far more than the discount.

BitBox is a hardware wallet made by Shift Crypto AG, a Swiss company. A hardware wallet is a small dedicated device that generates and stores the private keys controlling your cryptocurrency, and signs transactions internally so the keys never reach an internet-connected computer. It is not a place where coins are stored — the coins remain on their blockchains — it is the thing that holds the authority to move them.

The security design uses two chips: a general-purpose microcontroller running fully open-source firmware, paired with a dedicated secure element certified to EAL6+, a high assurance level for resistance to physical attack. The dual-chip approach means compromising the device requires defeating both, and the open firmware means the code can be audited by anyone rather than taken on trust.

The companion software is the BitBoxApp, also open source, available for Windows, macOS, Linux, Android and iOS.

The established model, with an OLED display and USB-C connection. It remains the cheaper of the two and does the same core job as its successor. For a desktop-first user this is the sensible default.

The newer device, adding a scratch-resistant glass display and Bluetooth connectivity, which brings iPhone and iPad support. It sits roughly a quarter above the BitBox02 on list price. The question to ask is whether you genuinely intend to manage funds from an iPhone; if you do not, the extra cost buys a nicer screen and a radio you will not use.

On Bluetooth specifically: adding a wireless interface to a security device makes some people uncomfortable in principle. The counter-argument is that transaction details are still confirmed on the device's own screen and buttons, which is the part of the security model that actually protects you — the communication channel is assumed hostile by design. It is a reasonable trade, but if you prefer a device with no radio at all, the standard BitBox02 is that device.

Both models come in two firmware editions and this is the more consequential choice.

The Multi edition supports Bitcoin, Litecoin, Ethereum, Cardano and a large number of ERC-20 tokens. The Bitcoin-only edition runs firmware that supports Bitcoin and nothing else.

Bitcoin-only is not a lesser product. Stripping out multi-asset support removes a large amount of code from the device, and less code means a smaller attack surface. If you hold only Bitcoin, the Bitcoin-only edition is the more defensible choice on security grounds, and it is what many long-term holders select deliberately.

The honest limitation of the Multi edition is coverage. BitBox supports a curated set of chains rather than the sprawling asset lists of some competitors. If your portfolio spans many alternative networks — Solana, Cosmos chains, various layer twos — check each one against the current support list before buying, because BitBox may simply not handle them.

The shop prices in several currencies including euros, francs, pounds, dollars and Bitcoin, and accepts card, Bitcoin and various European bank payment methods. Import duties are stated as included at checkout, which removes the unpleasant surprise of a customs bill on delivery.

A hardware wallet is one of the few purchases where where you buy it is part of the product. Buy only from the official shop or an authorised reseller. Never buy a hardware wallet second-hand, from an auction site, or from a marketplace listing by an unknown seller — a tampered device that arrives with a pre-generated recovery phrase is a known and repeatedly executed attack, and no amount of packaging inspection reliably detects a sophisticated one.

Set the device up yourself from a factory state and let it generate the recovery words in front of you. If a device arrives with a recovery phrase already written on a card, it is compromised — that is not how these products work.

Write the recovery words on paper or, better, stamp them into a metal backup, and store them offline. Never type them into a computer or phone, never photograph them, and never enter them on any website. No legitimate support agent, giveaway, airdrop or promotion will ever ask for them. A discount code is a string you type at a shop checkout; a recovery phrase is the entirety of your funds, and the two should never be confused.

Finally, understand the responsibility you are taking on. Self-custody removes the counterparty risk of leaving coins on an exchange, but it replaces it with your own operational risk. Lose the device and the backup and there is no recovery process and no company that can help. That is the point of the product, and it is not for everyone.

Be proportionate about what 5% is. On a device in this price range it is a few euros — worth applying, since it costs nothing, but not a number that should influence which hardware wallet you buy or whether you buy one at all.

The reason to choose BitBox is the engineering: open-source firmware, a certified secure element, a Swiss company that is straightforward about who it is, and a Bitcoin-only option that meaningfully reduces complexity for the largest group of users. Decide on the model and edition on those grounds, buy direct from the official shop, and apply MADTRADES on the way through the checkout.
