Side-by-side comparison
| Feature | Trezor Safe 7 | Ledger Flex | Tangem Card |
|---|---|---|---|
| Best for | Long-term Bitcoin + serious multi-coin holders | Active crypto users with lots of tokens, DeFi, NFTs | Normal humans who just want “a Bitcoin card” |
| Screen & UI | Nice bright touchscreen, easy to read & navigate | Full touchscreen device, polished Ledger UI | No screen — you approve via phone app & NFC tap |
| Seed phrase | Standard BIP-39 seed phrase you write down | Standard recovery phrase with optional advanced flows | Can be used seedless by default, or with optional backup phrase |
| Coin support | Great for BTC and most majors (see trezor.com for full list) | Huge list of chains, DeFi, NFTs (Ledger specialty) | Most people will use it for BTC & a few majors |
| How you sign | USB-C, confirm on device screen | USB-C / Bluetooth (depending on device), confirm on screen | Tap card to phone via NFC and approve in app |

My actual recommendations
Cold storage pick
Trezor Safe 7 – “Grown-up” cold storage
If you want a real hardware wallet that feels mature and boring-in-a-good-way, Safe 7 is it. I like it as the “park it and forget it” device for savings you actually care about.
- Touchscreen, easy to see what you’re signing.
- Full seed phrase backup — the classic cold storage pattern.
- Strong Bitcoin support plus solid multi-coin support.
- Good fit if you’re the “I’ll still have this 5–10 years from now” type.
Power-user pick
Ledger Flex – For people deep in crypto
If you’re juggling a bunch of chains, staking, DeFi, NFTs, and random tokens you can barely keep track of, Ledger’s ecosystem is built for that life.
- Touchscreen device with Ledger’s usual app integrations.
- Great when you’re constantly doing on-chain things, not just parking BTC.
- Big ecosystem: lots of wallets, services, and apps know Ledger.
- More moving parts than Trezor if you just want dead-simple cold storage.
Simplest pick
Tangem Card – The “just tap it” wallet
Tangem is basically “a crypto card you tap with your phone.” It’s the one I recommend to normal people who don’t want to become hardware-wallet nerds.
- Lives in your physical wallet like a credit card.
- Use the Tangem app, tap to sign — no cables, no screens.
- You can choose to use a seed phrase or go seedless depending on comfort level.
- Perfect for day-to-day and medium-term holdings, not max-paranoia cold storage guy.
Which one should you actually buy?
If you’re the kind of person who will happily sit down, write a seed phrase carefully, and store it in a safe place, Trezor Safe 7 is your best “grown-up” option.
If you’re already running a small zoo of tokens, chains, and weird on-chain experiments, Ledger Flex plugs into more of that world and will feel more natural.
If you just want to own some Bitcoin without becoming “that crypto guy” in your friend group, Tangem card is usually what I’d hand you first.
None of this is financial advice. It’s just what I’d tell a friend over coffee who asked, “Okay, which wallet should I buy and why?”
