`shasum` 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

patio11 / react-flummox-reduce-boilerplate.js
Created June 26, 2015 13:39
Got tired of all the boilerplate with hooking up Stores/Actions so...
// When I was working on our React/Flummox app I got to the point where, per the docs, I had ~100 lines of code
// which were substantially predictable boilerplate, so I used some JS metaprogramming to condense them by 80%.
// Flummox docs:
// I use underscore.js below for utility but you can also just do a for loop.
