This is incredible! What actually stops me from launching such an attack on something like Einsteinium?
One problem I found w/ the website: you have included Peercoin, even though Peercoin uses PoW only for initial coin distribution and not block validation. Block validation is done through PoS.
This! Einsteinium would apparently cost $33 to attack? Even if it's off by an order of magnitude or two (as some of the other comments seem to suggest), this _still_ seems like something a security researcher could/should try.
(Not to steal peoples' money but rather just to prove security or lack of it!)
