Are Stablecoins Actually Safe? What to Check

By Gurjeet Singh, developer of CoinPriceAlert · Published 9 August 2026 · 3 min read

Three designs with three different risks

Fiat-backed stablecoins hold reserves — cash and short-term government debt — and are as good as those reserves and the issuer's honesty about them. Crypto-collateralised stablecoins are backed by over-collateralised crypto positions and carry smart-contract and liquidation risk. Algorithmic designs attempt to hold a peg through mechanism alone, and the history of that category includes some of the largest failures in crypto.

These are not variations on a theme. They fail in completely different ways and should not be treated as interchangeable because they share a price.

What to actually check

For a fiat-backed coin: who holds the reserves, what they are held in, how often it is attested, and by whom. An attestation from a recognised firm published monthly is meaningfully different from a self-published statement. Short-dated government debt is meaningfully different from commercial paper of uncertain quality.

Also check redeemability. Can you actually redeem for cash, and at what size and cost? A peg maintained only by market makers rather than by real redemption is weaker than it looks.

The practical posture

Treat stablecoins as a tool for moving between positions rather than a place to store savings. A depeg is fast, and being large in the wrong one at the wrong moment has cost people real money multiple times.

If you hold meaningful balances, spread across issuers rather than concentrating, and set an alert on the price. A stablecoin alert sounds absurd until the one time it is the most valuable notification you receive.

The mistakes that cost the most

Over-alerting. Forty alerts is not forty times the coverage of one — past a certain density, additional alerts reduce total attention rather than increasing it.

Reacting to a move without checking what caused it. A fall that happens while the whole market falls is a different event from a fall that happens alone, and the correct response differs completely. Checking correlation first takes ten seconds and prevents most panic decisions.

Changing the plan mid-move. The level you chose while calm is better than the one you will choose while watching a candle. If you find yourself widening a stop or moving a target during volatility, that is the moment to close the app rather than the moment to act.

Never reviewing. Most people set up stablecoins once and never look at whether it worked. A short monthly review — what fired, what you did, what you would change — compounds faster than any refinement of the setup itself.
