Sound Assets
Editorial thesis section
  1. 1. Our thesis, stated up front: we believe Bitcoin is the most sound asset humans have ever had access to. This section argues that thesis.
  2. 2. Our holdings: We hold bitcoin as an asset.
  3. 3. We make no price predictions, ever: not for BTC, not for hotels.
  4. 4. BTC has 17.8 years of history (genesis block January 3, 2009 ↗); statistical claims carry that caveat.
  5. 5. No sponsorships from bitcoin-industry companies; if that ever changes, the disclosure goes at the top of the page, not in fine print. Sponsorship policy

Evidence register

The standing catalog of evidence for and against the thesis. Each entry carries a direction, a strength grade, a source and the date it was added.

Append-only: entries are never edited or deleted. If an entry turns out to be wrong, the correction is logged on the errata page and a new entry is added. Strength: strong = verifiable source, directly tests a soundness criterion; moderate = relevant but partial, indirect or secondary-sourced; weak = suggestive only.
