It feels like you're reacting to something I didn't say. Did you hear me say "Nano will replace Bitcoin"? (I know non-autistic people hear a lot of things by implication even if they weren't intended, it's a constant hazard to communication but I won't hold it against you)
Edit: I suppose I am hearing you say that if Nano cannot compete, then there's no point in using it. Which you didn't say. Perhaps I missed the meaning and purpose of your first point? Without implied meaning, your comment seems not to be really related to my post.
