Actually “Em-Tee Gox” is the original pronunciation and I was just trying to be true to history for the audiobook. It shifted to “Mount” over the years simply because it looked that way.

But MtGox originally stood for “Magic the Gathering Online Exchange.” It started as a tradable card game service that eventually added bitcoin. Then at some point they updated branding and people had already been calling it “Mount” at that point and it stuck.

I don’t think there was a specific time when it shifted but in thinking about it I went with the original that we would say way back in the day before mount became the norm. The play on “empty” feels appropriate as well. 😆
