I create stuff.
Pertinent to Nostr, I set up the Nostr Wiki - It's a wiki and it could use your help. No account needed, just edit.
Most pertinent to BTC, I made the (1) Satoshi Bitcoin Converter, (2) I edited Kicking the Hornet’s Nest: The Complete Writings, Emails, and Forum Posts of Satoshi Nakamoto, the Founder of Bitcoin and Cryptocurrency - all of Satoshi's public writings in order, and (3) for fun, Bitkenstan.
