I’ll start with what I know:
ASICMINER by friedcat - alive and paying dividents, not currently listed on an exchange (pass thoughts exist)
https://bitcointalksearch.org/topic/asicminer-entering-the-future-of-asic-mining-by-inventing-it-99497
MOORE by friedcat – alive, but understandably not friedcats main focus right now
nastymining
Lots of stuff recovered here: https://btct.co/
If you owned shares of any of the assets you see there, and you did not receive an email from BTC-TC when the list was imported, please PM me. Google, Yahoo, Hotmail, etc, put a lot of our initial emails in the spam folder.
Cheers.
