Not dead markets, but not very active ones by the time the death of this project occurred. I'd have to review the code to see how it calculated a 'cash out' value, exactly, but IIRC, it basically just took the highest bid to convert to bitcoin/eth or whatever and summed up everything. It was entirely naive af, for sure. Probably because I assumed that my future self wouldn't essentially sell off everything in 30 minutes.

Also, I still know of at least two projects that I wrote, running since 2012 with very little maintenance ... knowing how to write resilient software and being clairvoyant aren't mutually exclusive.
