SHANGHAI, Dec 29 (Reuters) - China's central-bank digital currency is little used, a former official of the People's Bank of China (PBOC) said on Wednesday, financial news outlet Caixin reported.
"The cumulative circulation of the digital yuan in the two years of the trial has been only 100 billion yuan ($14 billion)," he said.
Central bank digital currencies are digital tokens, similar to cryptocurrencies, issued by central banks.
"What needs to change is the digital yuan acting only as a substitute for cash and only for consumption," Xie said.
To address the problem, usage of the digital yuan could be expanded - for example, by letting individuals buy financial products with it, Xie said.
