I'm sure about that and that's why bitcoin place is same like commodity ( gold, silver, index's, etc ) not with currency. All economy activity should ended with currency so let's avoid bitcoin will replace real money, that's wrong. Even we see bitcoin is more popular than forex ( currency ) but bitcoin is similar with commodity, need to mining and can sell in market the different is only about equipment. Similar movement yes, so why not use gold indicator to predict bitcoin direction?.
