Zimbabwe began trading a new currency today, Tuesday, to replace the local currency, the Zimbabwean dollar, which has suffered from a decline in value and frequent refusal by citizens to use it. The new currency "Zig" was initially introduced digitally in early April, but cash notes and coins for this currency can now be used. "Zig" represents the latest attempt by the southern African nation to halt a prolonged currency crisis that reflects its ongoing economic problems. The government had previously proposed various ideas to replace the Zimbabwean dollar, including the introduction of gold coins to curb inflation and even experimenting with digital currency.
