Duress Wallet Features With Pin games
Duress Pin
Coldcard Wallet provide an optional “duress PIN code”. If you enter that PIN code, instead of the “real” PIN code, nothing special is shown on the screen and everything operates as normal… However, the bitcoin key generated is not the main key. It is effectively a completely separate wallet!
To take best advantage of this feature, you should put some Bitcoin into the duress wallet. How much you are willing to lose or what you need to make it plausible, we don’t know.
The “duress” wallet will still be derived from the original BIP39 words, so you don’t need to back it up separately, but there will be no way to get from that wallet back to the original wallet with the real funds in it.
Countdown To brick Pin
This is a covert variation on the BRICK ME PIN mode. It forces a time delay (of minutes/hours/days) when logging into the Coldcard.
But Once set, unlike the normal countdown, this special mode covertly bricks the Coldcard. Again, this may form some part of your game-theory for duress situations, but is completely optional.
Coldcard Wallet goal of this mode is provide plausible deniability of a required time delay (similar to Bank’s safes), while denying the attacker a functional device in case they take it away.
Benefits of a Cold Storage Wallet
Hardware wallets are designed to be unhackable. They keep your cryptocurrency safe because every transaction must be approved by physically pushing a button on the device. Theoretically, you should be able to plug your hardware wallet into a virus infested computer without much risk to your funds.

Instead of having to write down and copy seed phrases for a bunch of different crypto wallets, it’s possible to write down the seed phrase for just the hardware wallet and then restore all of the other crypto wallets loaded on that device.
As a rule of thumb, if you have crypto that’s worth more than the cost of a hardware wallet you should probably invest in a hardware wallet. With that in mind, let’s look at the Coldcard and what makes it different from other crypto wallets.

Offline Transactions
The Coldcard is specifically designed to allow for transactions without using the internet. While it is possible to use other hardware wallets without connecting them to the internet, the process is more difficult given that they don’t have a Micro-SD card slot like the Coldcard does.
