About "for every rise there is a fall", well, that was Newton. With Bitcoin we are now past Einstein and there are new laws at play. In Bitcoin mathematics, there are only the (+) and (*) operators and no negative numbers. LOL!
Oh Bitcoin may fall. As it's zinging through space long past the moon it might eventually hit some star somewhere and "fall"....
I'd put the odds at 50% of this happening before the heat death of the universe. We'll have to wait and see....
