Cryptocurrencies can't work as real currencies as they don't provide stable stores of value,UBS ' chiefeconomist said.- People have "absolutely no certainty" of what they can buy with them tomorrow, UBS'
Paul Donovan said. - The fundamental flaw is that there is no balance between supply and demand.

"Proper" currencies should provide a stable store of value with the certainty that they can be used to purchase the same basket of goods today as they can tomorrow," he said. "With
A fundamental flaw with cryptocurrencies, Donovan said, is that there's no balance between supply and demand for digital tokens.
Central banks are able to reduce supply when demand falls for a proper currency, thereby maintaining both balance and spending power, he said. But when demand falls for cryptocurrencies, supply cannot simultaneously go down, causing the value and spending power to rapidly collapse.
