WOW THIS IS REALLY HELPFULL. COULD U PLZ UPLOAD A VIDEO ON ATOMIC ORBITALS?
So far I found the first video confusing as hell, but the last two helped me get an overall concept of bitcoin security. This is a long series tho, so to be continued tomorrow..

There is one reserved especially for you in Hell.
Is there a cartoon or sing along version explaining this? Maybe a book with pictures I can trace along?
