I only just now realized that a BitCoin/Cash trader by the name of Mike Hoyne who corresponded with in 2015 must have used an alias:
Yet I was at first puzzled to turn up some Mike Hoynes who were variously British Sports Car Collectors as well as Marathon Runners.
Yet I was completely unable to google the Mike Hoyne who deals in crypto.
This leads me to advance my hypothesis that for every anonymous nick there is one or more live humans who have that same name.
I'll put off until I complete on my contract my search for the poor bastard whose parents quite lovingly and quite proudly named him Goatse Cx.
