this issue is quite shocking to the world, maybe there is no other option for Venezuela to get out of its economic crisis all this time, because the Bolivar as its national currency is worthless, just imagine you have to pay a few million bolivars to buy a cup of coffee, this doesn't make sense .
but I've heard the news that now Venezuela has issued a new national currency by eliminating some zero digits behind the value of money, I think this method is quite unique but invites pros and cons.
