What are Stablecoins? Are they Solution to Cryptocurrency Problems?
Mark Tencaten explains that the utility of Bitcoin (BTC) and other virtual currencies as a means of exchange has been constrained by price volatility, which is why stablecoins, a more recent breed of cryptocurrency, are becoming more and more popular.
The
list of stablecoins has expanded since Tether (USDT) became the first one in
2014. In addition to Tether (USDT), Havven's Nomin, True USD (USDT), Paxos
Standard, USD Coin (USDC), Digix Gold, and Binance USD.
What are Stablecoins?
A
currency is most helpful when it serves as a means of exchange and a store of
value, regardless of whether it is the U.S. dollar or Dogecoin. For those
activities, price stability is essential. Because of this, authorities work to
maintain a general level of stability in the prices of traditional national
currencies. A daily movement of 2% in the forex market of fiat currencies is a
massive shift.
Mark Tencaten
says that this does not happen in the Bitcoin world. During mid-November and
mid-December of 2017, Bitcoin, the most well-known cryptocurrency in the world,
soared from less than 6,000 dollars to more than 19,000
dollars before dropping to roughly 6,900 dollars by early February
2018. More recently, it increased from 5,000 dollars in March 2020 to
44,000 dollars by August 2021, a significant increase. It is not unusual
to see cryptocurrencies increase or decrease by 10% over the course of a day,
even on an intraday basis.
Such
large swings are not indicative of a stable currency. This has raised
significant concerns about whether well-known cryptocurrencies serve any
purpose other than speculation.
Stablecoins
are a new type of cryptocurrency that intends to offer the price stability
needed to promote widespread use. The best of both worlds is what stablecoins
promise bitcoin supporters: stable valuation without the centralized control
associated with cash.
How do stablecoins maintain
their value?
Stablecoins
aims to reduce volatility by fixing their price to the U.S. dollar and securing
the worth of their units with liquid sources of collateral.
Mark Tencaten
explains that stablecoins can be split into three categories based on how they
decide to pursue price stability.
1.
Stablecoins with fiat
collateral:
The valuation of these stablecoins is supported by fiat money, such as the U.S.
dollar. Precious metals like gold and silver, as well as commodities like crude
oil, can also be used as collateral. To ensure that the stablecoin tokens are
redeemed, collateral needs to be stored by a custodian and constantly audited.
Popular stablecoins Tether and TrueUSD are supported by
dollar reserves and are linked at par with the U.S. dollar.
2.
Stablecoins with crypto
collateral:
Stablecoins that are crypto-collateralized are comparable to those that are
fiat-backed, but their underlying collateral is a different cryptocurrency or a
collection of cryptocurrencies rather than a fiat currency or a physical good.
Stablecoins backed by other cryptocurrencies are typically
"over-collateralized," which means the value of the collateral
exceeds the value of the tokens issued by a certain ratio to account for the
negative effect of the collateral cryptocurrency's volatility.
The collateral for the Dai stablecoin is a collection of digital
assets valued at 150 percent of the token value. It is tied to the value of the
dollar.
It's a flawed system. The stablecoin's value will crash,
contradicting its purpose; if the collateral cryptocurrency entirely fails,
there are procedural problems with the auditing procedure, or demands for
further top-ups of collateral are not delivered on schedule.
3.
Algorithmic stablecoins: Algorithmic stablecoins,
whether collateralized or not, depend on an algorithm, or a system of rules, to
regulate the supply of tokens and maintain their value.
An algorithmic stablecoin might, for instance, rely on a rule
requiring adjustments to the token supply necessary to preserve the
stablecoin's value. This is comparable to a central bank's responsibility to
change interest rates to maintain price stability. The key distinction is that
central banks, such as the U.S. Federal Reserve, establish a monetary system
based on generally accepted guidelines and support it with an infinite supply
of legal money. Such benefits are absent with algorithmic stablecoins like
Basis and TerraUSD.
