Whoa. Never buy a closed source hardware wallet bought from a third party. Trying to save a few dollars could mean you buy a device that's been tampered with, even if it's sold as new. I wouldn't even buy an open source hardware wallet from a third party.

yeah i know its not recommended. i thought the worst thing that could happen is they fill in the seed phrase for you hoping you won't generate a new one. i heard about that scam but apparently there's other scams.

The worst thing that could happen is hackers figure out how to add their own electronics into the device to steal your coins. Or the seller puts your name and address on a list of people to rob. Ledger got hacked and the hackers leaked their entire customer database a while back, including customer names, email addresses, phone numbers, and home addresses. Here's how that went:

Don't take risks when setting up your Bitcoin security. If you buy a hardware wallet, buy it directly from the company or go DIY using an off the shelf device (like a Raspberry Pi or one of these Kendryte K210 devices).

Seriously, don't take risks when setting up your Bitcoin security.

Maybe you're thinking "Hang on! You said to buy a Yahboom from AliExpress!" The Yahboom K210 Visual Module is not a hardware wallet. It's a mini computer that runs micro python & can be used for any purpose. It's not a hardware wallet until you load hardware wallet software onto it. At some point, I may buy myself a backup Yahboom, but next time, I'd buy it with a robot kit for the fun of it. When I want to use it as part of a robot, I'll flash the robot code onto it. When I want to use it as a hardware wallet, I'll flash Krux onto it. It takes less than a minute to flash Krux onto one of these devices. You download Krux from Github and follow the instructions. Or, I think they have an installer too, but I just run a command in Terminal to install it.

why not just buy a second yahboom for the robot thing. seems like it would be a hassle having to switch back and forth between the robot and bitcoin wallet.

I meant, I'd buy a second one as a spare. I'm big on having a backup, just in case. It takes less than a minute to install Krux on a device, so it's not a hassle. Plug the device into your computer, paste one line of code in Terminal, and a few seconds later it's done.

anyhow i had never heard about this yahboom and krux thing it must be some highly kept secret but it's exactly what i have been looking for i think Shocked

Krux and Yahboom are totally different things. Think of it like software and a computer. Krux is the software. Yahboom K210 is the computer. Kind of like how you run Adobe Photoshop on a Mac or on a PC. You run Krux on a Yahboom K210 or on a Maix Cube.

Krux is a relatively young project. It's a few years old, but it really started making big progress last year. I think that's when they started winning grants from OpenSats to fund their work. I've been mentioning Krux a lot because it's so much better than any other hardware wallet I've seen or used. And it has some features that I think greatly increase security. Encrypted seed QR is a game changer. Passphrase QR is a game changer. And the ease of switching the network from Bitcoin Mainnet to Testnet makes testing your security so easy. Mainnet is the main Bitcoin blockchain we all know and love. Testnet is a testing version where coins have no value, because it's just for testing. Experimenting with Testnet is such a great way to learn. I wish every Bitcoiner would do it!

The Yahboom K210 Visual Module is just one of the devices Krux can run on. If you have really good vision and don't mind not having a touchscreen, Krux runs on a Maix Cube, and those things can sometimes be found for as little as $35. But it's a tiny screen, and it has a crappy toggle button like a Blockstream Jade that's obnoxious to use. For just a few dollars more, the Yahboom is so much better. Sadly, the best device for Krux has been out of stock for months: the Maix Amigo. That thing cost $50 and has a 3.5 inch touchscreen. It's awesome. If the Amigo ever comes back in stock, I'm buying 2 of 'em.
