The pros and use cases are all theoretical though. With nothing to stabilize the price it will continue to fluctuate wildly. From the examples you provided: if that man deposited his savings into Bitcoin last week, and had to withdraw today, he would be at an enormous loss. Not everyone is in a position to 'hodl'. If Venezuelans deposit their weekly paycheck into Bitcoin, but have no way of spending it on tangible goods - they still need to convert back into their domestic currency. The only thing that changes is now they pay transaction fees. Yes - the technology can solve some issues. But not how it is currently implemented.
