That’s the same timeframe as the one used in the article, and sure, they could have made it explicit again, but implicitly it makes sense because it’s the one that’s useful for a direct comparison.
Turns out, the implicit timeframe that should be clear after reading the article was the right one, and it’s pretty damning for bitcoin as is. So again, I am not sure what point you want to make.
I’m on the side of Retiring@lemmy.ml here, since I read the comments before the article. Without the articles’ context I had no idea if this meant all-time usage, per year, or per month.
Since the link is right there though, which says per year, it’s really not a huge deal.
