As for Anonymint's coin, correct me if I'm wrong, but I think he's relying on people not being able to create an ASIC with more than 200% efficiency of a CPU or the entire model fails?
1. He said order of magnitude. In normal English that usually means 10x, though binary order of magnitude -- 2x -- also means something occasionally. I'm not sure what 3x means.
2. I don't think he said the entire model would fail otherwise, so that may be your made up conclusion. I don't really remember though, he may have suggested that.
