You don't need to spend $200+ for cold storage. These five hardware wallets — Trezor Safe 1, Tangem, BitBox02, CoolWallet Pro, and Ledger Nano X — all deliver offline key security under $100. Here's how they compare on form factor, open-source status, and ease of use.
You don't need to spend $200+ to keep your crypto keys offline. Several reputable hardware wallets come in well under $100, trading premium features like touchscreens and Bluetooth for rock-solid cold storage at a budget price. Here are the best sub-$100 options.
Under $100, you're still getting the core security promise of a hardware wallet: offline key storage, PIN protection, and either a secure-element chip or open-source firmware you can audit yourself. What you typically sacrifice are large color touchscreens, premium build materials, and sometimes Bluetooth connectivity. For most people, those are nice-to-haves — the actual security lives in keeping your private keys air-gapped, and every wallet on this list does that.
The Trezor Safe 1 is the wallet for purists who want verifiable security without paying a premium. Its firmware is fully open-source, meaning the code can be independently audited — a rare feature at this price point. Physical buttons handle confirmation, and it supports 9,000+ coins through the Trezor Suite desktop and web app.1
At roughly $49–69, it's the most affordable wallet on this list and arguably the best value. You give up Bluetooth and a color screen, but you get the same fundamental cold-storage security as Trezor's higher-end models. If you want to verify exactly what's running on your device, this is the pick.
Tangem takes a completely different approach: it's a card-shaped hardware wallet that uses NFC to communicate with your phone. There's no seed phrase to write down, no battery to charge, and no screen — you just tap the card against your phone to sign transactions.2
This makes it the simplest hardware wallet to use, period. The trade-off is philosophical: some users are uncomfortable with a wallet that doesn't expose a standard recovery seed. But for beginners who want hardware-level security without the intimidation of seed-phrase management, Tangem is hard to beat at around $50–70.
The BitBox02 is a USB-C-only wallet from Swiss company Shift Crypto. It's open-source, features microSD backup for easy recovery, and has a clean, minimalist design that appeals to users who want a no-nonsense device.3
At roughly $90–99, it sits at the top of the sub-$100 range. It's best suited for Bitcoin and Ethereum users — its coin support is narrower than Trezor's. If you primarily hold BTC or ETH and want a beautifully simple, open-source device from a privacy-conscious Swiss company, the BitBox02 is worth the extra money over the Trezor.
The CoolWallet Pro is designed for people who want hardware security on the go. It's literally the size of a credit card and fits in a physical wallet. Unlike most sub-$100 options, it includes Bluetooth pairing, making it a genuinely mobile-first device.4
At around $80–99, it bridges the gap between a software wallet's convenience and a hardware wallet's security. The trade-off is that Bluetooth adds a small attack surface compared to USB-only or NFC-only devices. If you're frequently transacting from your phone and want hardware-level signing without carrying a USB stick, the CoolWallet Pro is the most practical pick.
The Ledger Nano X is one of the most widely used hardware wallets, with Bluetooth connectivity and a large coin ecosystem. While it typically retails slightly above $100, it frequently goes on sale under that threshold, and the Nano S Plus variant is regularly priced under $100.5
It's worth mentioning as a mainstream alternative, though it doesn't fully meet our sub-$100 criteria at standard pricing. Ledger uses a secure-element chip but its firmware is not fully open-source — a key difference from Trezor and BitBox02. If you value brand recognition and a polished mobile app over open-source verifiability, and you can find it under $100, it's a solid choice.
| Feature | Trezor Safe 1 | Tangem | BitBox02 | CoolWallet Pro | Ledger Nano X |
|---|---|---|---|---|---|

For under $100, you're choosing between three philosophies: open-source verifiability (Trezor Safe 1, BitBox02), radical simplicity (Tangem), or mobile convenience (CoolWallet Pro). All of them deliver the core promise — your private keys never touch an internet-connected device. Pick the form factor and workflow that match how you actually use crypto, and you'll get solid cold storage without breaking the bank.
