Like many powerful currencies in the past, USD may fall to ground too, my question is will that effect BTC value? Or is it independent of all other real world or non digital currencies of the world?
I believe that bitcoin does not depend on the price of the dollar. In other words, the dollar cannot affect bitcoin. We certainly trade in this currency pair and understand that everyone is guided by the dollar as an international asset. However, this is only an indirect understanding of this dependence.
Bitcoin do not have any concern with USD or any other fiat currency, therefore I personally do not think that if USD will fall it will affect bitcoin price. Bitcoin is no doubt becoming the main currency of the people which they will not online use for online purposes but will also use it in their offline shopping shops.
