- ricklamers 10y agoKind of what I expected, thank you for referencing SDCH. Directs me to more interesting reading material. Edit: Found this: https://aprescott.com/posts/sdch https://aprescott.com/posts/sdch Maybe SDCH isn't that useful after all? Looking to find some quantitative data on potential gains from SDCH now.
