I heard this from this asian conspiracy theorist from many years ago like 2011, he said in the future there WILL be a one universal currency. Which he meant every where in the world will use that currency and other currencies will disappear. But this universal currency where will it come from? bitcoin or from the fed? I think in the future there will be 2 universal currencies, that 1 is the bitcoin and the other will be from the fed. So what do you think will happen if most of the world jump onto bitcoin? 
well I dont think so bitcoin can ever go down or it is going to be late ever to buy bitcoins as we know the price has decline and now it is the good time to buy bitcoin because the price of the bitcoin will surely start going high in next week I think after august first but you should not wait too longer because the price will start increasing soon price is going to increase after august first.
