exchanging coins for goods and services, though rather than the familiar round minted shape

we're used to today, these “coins” were cast in the shape of shells, or miniatures

of common tools like spades or knives. So, it might be fitting that the first country

that could abandon physical money in favor of digital legal tender is China again. How

will it work, what are the pros and cons, how is it different from cryptocurrency, and

what does this mean for the rest of the cash-using world? Part of the reason China has taken

the lead creating a state-backed digital currency is because they initially lacked the credit-card

based payment infrastructure of other countries, like the U.S. So, tech companies like Tencent

and Alibaba developed apps that let people exchange money digitally with their phones.

The apps have proven extremely successful, with hundreds of millions of Chinese citizens

using them regularly. Six years ago, China's central bank saw the upsides of developing

their own digital yuan. As of April 2020, the program is being taken for a test run

in four Chinese cities. The details on how the currency actually works aren't very

well known, but a few things are clear. The digital yuan is tied to the value of the normal,

physical yuan. Since it's state backed, that means the

government is liable for it and it should be stable, compared to cryptocurrencies like

Bitcoin, where the value can swing wildly. And because it's backed by the state, that

means it'll be more widely accepted. Already, nineteen companies including McDonald's

and Subway are participating in the trial. A major roadblock to the adoption of cryptocurrencies

has been their lack of government recognition and widespread acceptance. But cryptocurrencies

do have some benefits that China's officially sanctioned ebucks lack, especially when it

comes to privacy. A huge appeal of bitcoin and others like it

is the blockchain, an encrypted and decentralized ledger tracking where the money goes. While

the blockchain is public, anybody using it can remain anonymous.

But if China's central bank develops and distributes the currency, then they can see

exactly who is involved in every transaction. China has a notorious history of being a surveillance

state, and this could be another avenue to continue their monitoring methods. All of

these advantages and disadvantages to each approach have left the future of digital currency

up in the air, and it's anybody's guess what'll happen next. Will the digital yuan

spread globally because of its convenience and stability, or will the rest of the world

opt out of handing their financial data over to China? Will the U.S. government attempt

to digitize their own dollar? Nobody really knows the answer to any of these

questions yet, but fortunes will be won and lost as we find out. I'm no financial guru

but I will make this prediction: while a digital currency seems all but inevitable, not everyone

will have access to the technology to use it, and others will still prefer old-fashioned

physical money. Even if digital currency becomes widespread soon, cold hard cash isn't going

to vanish. At least, not right away.
