Comparing Bitcoin software & hardware wallets, seed backup solutions, nodes & books: http://thebitcoinhole.com Twitter: @thebitcoinhole
We had the chance to receive a prototype of the new Keystone 3 Pro. Thanks Keystone to trust us to analyze and review it. These are our impressions about it. ✅ Rounded bounds compared with the previous generation make it feel more comfortable. ✅ Reduced size and dimensions, keeping the same screen 4" screen size. ❌ Missing removable battery. This is something will miss compared with the previous generation. ✅ 2 years warranty compared to the 1 year offered by the previous model. ✅ The support to manage up to 3 unique seed phrases from a single device is awesome. We didn't find this feature in any of the other wallets we compare. ✅ The wallet setup is super easy. With the chance to easily switch between 12 and 24 words, and recreate new keys with just one tap. ✅ Possibility to sign transactions using USB data, Bluetooth or QR, covering the different levels of expertise. ✅ The same with the firmware updates. You can upgrade using the USB port or a MicroSD card. ✅4 ways to configure the device unlock and the access to different features: numeric PIN, alphanumeric password, fingerprint, or gesture. ✅ A dedicated software is used instead of Android, which gives more security to the wallet. ❌ The touch sensor works fine, but it could be a bit better. ❌Missing features like SeedQR support, ephemeral seeds, some advanced security PIN features, etc. ✅ Very good price ($129) for a wallet with camera, touch screen, fingerprint sensor and 3 secure elements You can see all the details of the Keystone 3 Pro on our website. You can also visit our comparison of more than 30 different hardware wallets.
BUG BOUNTY PROGRAM We want to have the most complete and accurate website to compare hardware wallets. Our goal is to help you to choose the correct wallet to buy. So, we are offering 5000 sats to each person that finds an error on our website. The rules: https://thebitcoinhole.com/bug-bounty
Lots of new features and improvements on our website where we compare more than 30 different hardware wallets. - New wallet details screen with detailed info, official youtube video previews, dropdown to compare the wallet against others, and much more. - Now you can compare wallets 1 vs 1. - Added links to Reddit and Telegram communities (when available) for each wallet. - More helpful info about each important feature of the different hardware wallets. - Data fixes and improvements
Storing your Seed Phrase in a digital document, taking a photo, a screenshot, or storing it in the cloud (like Google Drive, or a Password Manager) exposes it to online threats that could track your keystrokes or gain unauthorized access. Always store your Seed Phrase offline.
Your seed phrase is the key to accessing all your funds. Under no circumstances should you ever share your seed phrase with anyone. Nobody has a valid reason to request your seed phrase. #selfcustody #bitcoin
Improved our "Payment Methods" section on http://thebitcoinhole.com, so you know the different ways to pay for each hardware wallet on the official stores. It's so crazy to see that some manufacturers are NOT accepting Bitcoin to buy their wallets.
You can choose to memorize your seed phrase and discard all backups, believing that this eliminates security threats. Memorizing a seed phrase can be a powerful security tool when traveling across borders, but it also creates a single point of failure: you. #selfcustody #bitcoin
Generate your own entropy When creating your own keys, there are many ways to do it, since we just need a very long random number. One way is to use high-quality dice, like those found in casinos. Roll them several times to create a long random number. #selfcustody
Withdraw all your #Bitcoin    from exchanges or custody services When you have Bitcoin in an exchange or a custody service, they hold control over your Bitcoin. It is only when you withdraw your Bitcoin onto a set of keys that you control that you truly own it. #selfcustody
Let's talk about Reproducible Builds for Hardware Wallets firmware. Verifiable Source wallets let you inspect code for flaws, but pre-compiled software lacks a way to verify if it matches the source. Reproducible builds ensure that anyone can recreate identical copies from source code, build environment, and instructions. That's why is important for all wallet users to learn how to build the firmware and verify it before upgrading their wallets. If not possible for you, at least see if there are proofs of others doing that verification. One good place to find those proofs is This week on Twitter & Nostr @ICQ encouraged people to learn how to verify builds. This was a success, a lot of people could learn how to build and verify the Coldcard firmware. From we want to also collaborate. So, we added a new section "Reproducible Builds" on our website. There you can find for each wallet if they offer reproducible builds instructions and if there are proofs of verification on We encourage all the hardware wallet manufacturers (or anyone interested) to collaborate and automate proofs of verifications on According to our research: @Blockstream Jade, Coldcard, @BitBox, @Foundation Passport Batch 2, Trezor, KeepKey, @SeedSigner, and Specter DIY offers reproducible builds instructions and/or proofs of verification. Please help us with a boost. And remember: #LearnToBuild #donttrustverify
Added Bitkey to our website where we compare more than 30 hardware wallets. Still lots of questions about the wallet, so the info is not complete. thebitcoinhole.com
@jack @Thomas We have a website comparing more than 30 hardware wallets (https://thebitcoinhole.com/). We completed the form to test Bitkey, but meanwhile is there any chance to connect with someone of the team that can answer questions about each feature, so we can add Bitkey to our website?
