Bits about Money subscription management logic, substantially authored by Claude Code. I do not recommend using this

	# patio11 notes: This file was substantially authored by Claude Code.

	# I do not recommend using it; it is extremely customized to particular requirements of my own business.
	# My purpose for publishing it is to show technologists (and others) an actual sample of non-trivial live
	# code authored by a modern coding tool, so they can get a bead on code quality, style, and similar.

	# Spoiler: this is a lot of boilerplate and bookkeeping to solve a task which this engineer
	# would also tell you is dominated by boilerplate and bookkeeping.

	# Code substantially similar to this runs in production.

Created December 31, 2025 22:54

Jekyll plugin to enable publishing Markdown for LLM accessibility.

	# Jekyll plugin to generate .md versions of posts for LLM consumption
	#
	# For any post not opting out via `no_markdown_export: true` in frontmatter,
	# generates a .md file at the same URL path with .md extension.
	#
	# Only includes allowlisted frontmatter fields to avoid exposing sensitive
	# internal fields like noindex, seo settings, etc.
	#
	# (Claude Code wrote most of this, FWIW.) I release this work into the public domain. -- patio11

patio11 / bitfinex-03152019.md

`shasum bitfinex-03152019.md` is 938d939059a23aa84ce493db0c4d542748f849a7

Prediction as of 3/15/2019 JST:

Bitfinex is insolvent, for the Bitcoin economy's usual quixotic definition of insolvent.
This happened as a result of collateralizing Tether with BTC and other cryptocurrencies during the run-up.
Bitfinex / Tether treat whether Bitfinex held the collateral or Tether held the collateral as a material distinction, but that's ridiculous due to common control. The important fact: in 2018, ground truth diverged from "There is $1 in a bank account for every tether outstanding" to "There is $1 in a bank account and/or $1 worth of Bitcoin at prevailing prices available to Bitfinex for every tether outstanding."
This makes Tether synthetically long Bitcoin, via a receivable from Bitfinex. Bitfinex took the newly issued Tether and then, since this accounting shellgame appears to balance its books and leave it with surplus Bitcoin, either sold or lent the Bitcoin to short sellers during the run-up.
If Bitfinex simply sold the Bitcoin, they're doing relatively well for themselve
