mined a small coin called btcx for a couple weeks around feb 2018. the miner was a binary only ccminer fork you had to download from their site. it saved 613 files to my drive that nothing could ever open. i kept them because i figured they were wallet data but theyre not. got an llm to look at the header this year and its the same 16 bytes on all 613 files, doesnt match any known file format. it says theyre video in a 5 channel color format. been converting them and putting them up. theres a voice on them. no idea what languageheader is F5 A5 05 5A 5F F5 A5 05 5A 5F F5 A5 05 5A 5F 05 if that means anything to anyonehttps://youtu.be/xO_-J77mYRE hexdumps here if anyone wants to look at the raw datahttps://github.com/suebtwist/btcx-files
