LuxeLetterX

Send the world's most expensive digital postcard via BTC.

What it does

Everyone is trying to "revolutionize" tech. I got bored and built a genuinely useless product. LuxeLetterX is a $1,400 (0.02 BTC) digital postcard. No utility, no token. It adds a verified Bitcoin receipt to your greeting, so you can express your true appreciation not just with empty words, but with the unquestionable receipt of an expensive digital message. The price auto-increases to 0.05 BTC after 3 sales. A social experiment in ego. Will anyone actually buy this?

Once a customer has clicked the “buy” button, we take care of giving them a unique address, monitoring that address for transactions, then securely notifying your website once a minimum number of confirmations have been received. Oh, ya, and then we send you the Bitcoins :) The website is here: BitWillet: http://www.bitwillet.com and there is a demo on the front page. (full disclosure: BitWillet uses the Willet, http://dev.getwillet.com, platform, of which I…

    With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
