A hardware wallet designed especially for storing Steem tokens sounds like the perfect idea to pursue through a Kickstarter campaign. I'm sure there are enough talented developers and people with the requisite business skills out there to bring such an idea to fruition. The key to getting such a project under way is potential market size and a strong enough demand for the product as people begin seeking reliable cold storage solutions.
Ooh... that could potentially also be worked as a publicity campaign to help generate more attention towards Steem...
Yes I agree. I would like add to this idea by saying that Steemit should promote like crazy the advantages of monetization of user generated content and the ability to protect one's earnings through rock solid security schemes and storage solutions. The campaign should also be squarely aimed at users of Facebook, Instagram, Twitter, and Snapchat, non of which offer direct payment mechanisms for their users. Naturally, the action should seek to attract the best contributors from each platform and weed out, to the best extent possible, spammers and pesky trolls.
