Not all crypto is designed to bounce around wildly. Stablecoins are built to stay at a fixed price, usually $1. Sounds safe, right? Not always. Some have collapsed to zero in days. Let's unpack what stablecoins are, why they exist, and the bigger list of risks every crypto buyer should know before putting in a dollar.
What a Stablecoin Is Supposed to Do
A stablecoin is a cryptocurrency designed to hold a steady value, usually pegged to the US dollar — one stablecoin should always be worth about $1. People use them to move money around crypto exchanges quickly without converting back to regular dollars every time, kind of like keeping cash in a digital wallet instead of a volatile investment.
The most common type, called a "fiat-backed" stablecoin, is supposed to be backed 1-to-1 by real dollars or safe assets like short-term government bonds held in reserve. In theory, you can always trade one stablecoin for one real dollar.
In theory. The word "supposed to" is doing a lot of work in this lesson — because whether a stablecoin actually holds that reserve, and whether it's audited honestly, varies a lot between different companies and coins.
When Stablecoins Aren't So Stable
In May 2022, a stablecoin called TerraUSD, which wasn't backed by real dollar reserves but by a complex algorithm and a sister token, collapsed from $1 to nearly zero in days. Investors lost an estimated $40 billion. It's one of the biggest reminders in crypto history that "stable" is a design goal, not a guarantee.
Even dollar-backed stablecoins have had scares — briefly dropping below $1 when people worried about whether reserves were real or liquid enough. Regulators in the US and elsewhere have pushed for more transparency and audits, but rules are still evolving and vary by coin and country.
The lesson: just because something is labeled "stable" doesn't mean it carries bank-level safety. There's no FDIC-style insurance protecting your stablecoin balance the way there is for a savings account.
Exchange Risk: Where Your Crypto Actually Sits
When you buy crypto on an app, your coins often sit on that company's exchange, not fully in your own control. If that exchange is mismanaged or dishonest, your money can vanish. In 2022, the exchange FTX collapsed after it was revealed customer funds had been misused — billions of dollars tied up, with many users getting back only pennies on the dollar, years later.
This is different from a brokerage holding your stocks, which in the US has protections like SIPC insurance covering certain losses if the brokerage fails. Most crypto exchanges don't offer anything comparable.
Some crypto holders choose to move coins into their own private "wallet" for more control, but that comes with its own risk: lose your private key or password, and there's no customer service line to call — your money can be gone forever.
Scams, Rug Pulls, and Too-Good-to-Be-True Promises
Crypto's newness and lack of regulation make it a magnet for scams. A "rug pull" happens when developers hype a new coin, get people to buy in, then drain the funds and disappear. Fake celebrity endorsements, fake exchanges, and "guaranteed 20% monthly returns" schemes are everywhere on social media.
A good rule: if a stranger online (or even a friend) promises guaranteed high returns with no risk, that's a giant red flag — no legitimate investment, crypto or otherwise, can guarantee returns. Real investing, even in boring index funds, always carries some risk.
Before ever sending money anywhere crypto-related, research the project independently, check if it's registered with regulators, and assume anything promoted aggressively online deserves extra skepticism.
Try It: Build a Risk Checklist
Next time you see a crypto asset — stablecoin or not — run it through a quick checklist: Who's behind it? Is there a real audit of reserves? How long has it existed? What happens to my money if the company fails? Could I lose 100% of what I put in?
If you can't answer those questions confidently, that's your answer about whether to get involved. Compare that mental checklist to researching a stock using our how to research stocks guide — the habit of asking hard questions before investing applies everywhere.
