What is the potential advantage of using a
stablecoin for USD payments, as opposed to a regular bank account?
选项：
A.
Higher
exchange rate volatility
B.
More attractive payment instruments
C.
Greater regulatory oversight
D.
Lower fees through technological
improvements
解释：
Stablecoins market themselves as leveraging
blockchain technology to deliver safer and more efficient account management
and payment processing services, with efficiency gains that can be passed along
to customers in the form of lower fees. Higher exchange rate volatility is a
problem with cryptocurrencies in general, and stablecoins are designed to
address this issue by tying their value to an asset outside of their control,
such as the U.S. dollar. Pegging to the U.S. dollar can make stablecoin
liabilities more attractive as payment instruments, particularly to people
living in the U.S. who use the U.S. dollar as their unit of account. However,
the question specifically asks about potential advantages of using a stablecoin
for USD payments, so the correct answer is D.
