Metaphorically (and digitally) speaking, are there 3 Bitcoins? Was Bitcoin started on the 0 bit or the 1 bit? Is there a switch/flapper? A similar applies to the algorithm. Is there a periodicity that is predictable and controllable? I have not looked into these issues, however, are enough cause of concern to research... if I were planning a large investment.
wtf are you talking about, that made absolutely no sense. and sha-2 is widely used, nsa came up with it.
