Thanks guys for sharing your opinion and ideas. I will definitely prepare draft with more details.
Meanwhile let me briefly share my views:
Wearable hardware wallet I think will be perfect fit for the people who are actively doing cryptocurrency transactions, maybe when they are at work, while traveling or splitting bill with a friend (My friends like this), but instead of using convenient mobile wallet, they prefer to hold their money safe in their offline storage. This might be less common today but in the bright future, I believe this behavior will become more general, especially when most of the merchants will begin accepting cryptocurrencies.
For the customer I described, people who don't just keep their coins in cold storage (which can be locked in the home safe for years), but frequently spend it, I think current USB hardware wallets will have higher chance of loosing while carrying than the ring or locket.
Beside the convenience of using Ring Hardware wallet, it can maintain symbolic means of the jewelry as well, the reason why lots of people wear rings every day. imagine, How cool can it be your wedding ring storing Bitcoins.
For more information about the Startup I co-founded please check the following webpage:
https://cnick.io/ Currently the material we use for manufacturing the ring is natural wood.
We started two years ago and first launched the product in Georgia. We are inspired with an idea of making authentication absolutely effortless by uniting all the identification needs into the most convenient device. Now instead of following the traditional path of Visa/MasterCard payments, we want to join blockchain movement as we believe in the technology and want to contribute to the mass adoption.
