Verdict

Please note that we do not yet own a Blockstream Jade. Our verdict currently is based on available online resources only. We love the 100% open source approach and can’t wait to get our hands on one.

If your use-case is Bitcoin ecosystem only, this seems like a very good option to secure your valuable Bitcoin assets.

Disclaimer: Our impressions are based on a compilation of factors tailored to the average user’s perspective. It is also important to note that whether a feature is a “pro” or “con” can depend on your situation and preferences. What may be an advantage in one scenario could be a challenge in another, and vice versa. Therefore, while reviewing these points, it’s essential to consider your unique requirements and circumstances when making decisions. This list aims to provide an idea of what to anticipate, but it is not the ultimate guide to determining whether something will work for you or not.
