All other sites are scams – especially be wary of:

benumbs.cards & bennumb.cards & bennumbs.cards & benumb.cc & many more…

(it can be hard to notice the S and extra N if not careful.) 

Welcome to the real deal. 

Please bookmark this link — the other sites have simply copy/pasted our html and don’t actually have any cards to sell. 

They can be easy to fall for if you aren’t cautious!

Only a reminder: The Ledger {Hardware} Pockets runs on closed supply software program (firmware on the machine). I’d not use it. Don´t belief, confirm.



I don´t get cash from that firm.

  1. This keeps me up at night. We preach “not your keys, not your crypto”, but then put our coins on a closed source wallet.

    I can see more than 1 way this ends badly…
    There has to be a better way.

  2. I think that Ledger, Trezor, Bitbox, Coldcard and Jade are all good.

    Ledger has an hardware closed and limited by an NDA but it is the only one in which the signing operation occurs inside the secure element so that the key never leaves the secure environment.

    Coldcard and Bitbox are opensource (to my knowledge) and they have nuances in the way they manage the private keys and the signing operations even if the seed is always somehow protected in part by the secure element.

    Jade and Trezor are totally opensource but while Trezor has the keys onboard, Jade has the seed on a remote server which can also be your own.

    ANY of these alternatives are better than keeping and using your keys on a computer and doing it, is in my opinion better (under some aspects) than giving them to a third part.

  3. BitBox02 is open sourced, has a secure chip, and is easy to use. They also have a Bitcoin only version. When you order it, it comes in a tamper evident envelope, and you can back it up with both your seed words AND a memory card. It’s super easy to use and can be connected to your own node so you don’t have to rely on other nodes for transactions.

  4. No comment about Trezor being physically hacked?….Hmm I smell a bias.
    Sure Ledger is closed source but they have been in the game long enough that it they were going to rugpull they would have done it long ago.
    More troubling is both Trezor and Ledger are falling behind on new BTC technologies. Their products seem stuck in 2017.
    Take a look at coldcard for continuous product updates. These guys get it.
