Nowadays bitcoin is connected with banking process. If bank not available. People can't change Bitcoin.
What are you even talking about?!!
Bitcoin is not "connected" to anything, it is a stand alone currency that is working for over a decade. People don't need to exchange their bitcoin either, it is a currency that can be used just like any other currency meaning you get paid in bitcoin (you are in a signature campaign so you should already know it!!!) and you can directly spend bitcoin.
