That Ron & Shamir paper has been, in the main, discredited - they got so much wrong, and missed so much, that it's basically useless.  There's plenty of threads on it - read them.

You reference a website with a post entitled "Shitcoin: a Modest Proposal" - and which has a bitcoin donation address?  Seriously?

I may not know as much as I think I do - probably don't - but I know a hell of a lot more about bitcoin than you do.

I know why it exists, and you have no clue.
