Experts at Goldman Sachs Zack Pandle and Charles Himmelberg said that advanced monetary standards and, specifically, Bitcoin, can turn into a reasonable methods for installment in nations where conventional cash isn't adequately given.
If they are talking about countries who currently have hyperinflation like Venezuela then they might be wrong about it, you see in places just like this even any foreign currency is affected when use in that country, just by having a foreign currency doesn't mean it will be immune to inflation in that country. You see inflation here affects two things aside from the devaluation of money you will also encounter the increase in price for goods which is common when the supply runs out. So this means even let say the US Dollar is backed by its country it doesn't mean that it's value for that country will be the same all through out. Their statement might be partly through but it cannot be applied to all countries' respective economies.
Just take a look at reuter's article on how the US dollar was affected even if it was a foreign currency in Venezuela.
Since Venezuelan President Nicolas Maduro legalized the use of foreign currencies last year, they have increasingly become the norm in many aspects of life.
In border areas and major towns, doctors, merchants and even plumbers require payment in Colombian, Brazilian, U.S. or European currency.
But as basic goods become scarcer, even those able to pay in dollars are finding that inflation is soaring.
According to calculations by local firm Ecoanalitica, a basket of basic goods that would have cost $100 a year ago would now require $675 to purchase even in U.S. currency.
