Its because Bitcoin doesn't follow the rules or care about anything thats happening other than being the massive stud that Bitcoin is  Honestly there are probably so many reasons why the price has gone up/gone down here or there anytime anywhere but who cares, as long as bitcoin is still working and up and running 24/7 with the fixed 21 million coins we are golden Can you imagine where we will be in 10 years time? Holy smokes!!!
