Stablecoins Explained: How They Hold a Dollar (And When They Do Not)

Published 16 July 2026 · 6 min read

Fiat-backed stablecoins

These hold reserves in cash and short-term treasuries. The risk is custodial and regulatory, not algorithmic.

Crypto-collateralised stablecoins

Backed by over-collateralised crypto positions. They are transparent on-chain but vulnerable in violent crashes.

Algorithmic stablecoins and their history

Designs relying purely on incentives to maintain a peg have repeatedly failed, most infamously in 2022.

Depegs are usually liquidity events

A stablecoin trading at $0.98 often reflects a temporary imbalance rather than insolvency — but the distinction is only clear in hindsight.

Security habits that prevent the losses you cannot undo

A reversal costs you a percentage. A compromised wallet costs you everything in it. Crypto transactions are final, there is no chargeback, and there is no support line that can reverse a transfer. That asymmetry means security deserves more of your attention than strategy, and gets far less.

The essentials: a hardware wallet for anything you are not actively trading; a recovery phrase written on paper and stored physically, never photographed and never typed into a website; app-based or hardware two-factor authentication rather than SMS, which is defeated by SIM-swap attacks; and a permanent assumption that anyone contacting you about your crypto is attempting fraud.

The most common theft is not a technical exploit. It is a convincing message — a fake support agent, an airdrop that needs your seed phrase, a wallet-draining signature request — that persuades you to hand over access. No legitimate service will ever ask for your recovery phrase, and a portfolio tracker only ever needs a public address, which cannot move funds.

Timeframes: why the same signal means different things

The same chart tells four different stories depending on the timeframe you open it on. A 5-minute chart is dominated by noise, execution and short-term liquidity. A daily chart shows genuine supply and demand. A weekly chart shows the trend that actually determines multi-year outcomes. None is more correct — but mixing them is how people end up taking a long-term position and managing it on a 15-minute chart.

Match the timeframe to your holding period. If you expect to hold for years, intraday movement is not information you should be acting on, and watching it will only cost you the position. If you are trading a multi-day move, the weekly trend is context rather than a trigger.

A useful convention: use the higher timeframe to decide direction and whether to be involved at all, and the lower one only to choose an entry once that decision is made. Alerts fit this naturally — set them on levels that matter on the higher timeframe, and you stop needing to watch the lower one.

A short checklist to work from

Condensed into something you can actually use:

**Write the question first.** What specifically do you want to know? Vague monitoring produces vague results. **Define the condition.** A number, a percentage, or a relationship — something that is either true or false, not a feeling. **Decide the action in advance.** If nothing would change when the condition is met, do not set the alert.

**Size for the drawdown you can actually hold.** Not the one you hope for. **Check the market before reacting to the asset.** Most moves are not asset-specific. **Automate the watching.** You will not be looking when it matters. **Review monthly.** Delete what never fired and what you never acted on.

Seven lines, and doing them consistently will outperform almost any refinement of the analysis itself. The edge in this market is much less about knowing more than everyone else and much more about reacting worse than everyone else less often.

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 the fundamentals 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.

Turning this into something automatic

Anything that depends on you remembering will eventually fail, usually at the worst moment. You will be asleep, in a meeting, on a flight, or simply not thinking about markets on the day it matters. That is not a discipline failure — it is the normal condition of having a life, and any system that ignores it is badly designed.

So convert every conclusion from this article into a condition that can be watched for you. A level you would act on becomes a price alert. A move size that would change your view becomes a percentage alert. A whole segment of the market you cannot follow coin by coin becomes one bulk rule that scans it and tells you when something unusual happens.

Set them, then close the app. The point of the fundamentals is not to make you watch more closely — it is to let you stop watching entirely and still be there when it counts. CoinPriceAlert sends push notifications for crypto, stocks, metals and forex, with quiet hours so nothing wakes you at 4am for a move you would not have traded anyway.

Why the fundamentals matters more in crypto than elsewhere

Techniques borrowed from equities often break here, and it is worth knowing why. It never closes, so there is no overnight gap in which to think — the largest moves routinely happen while your part of the world sleeps. It is far more volatile, so a position sized like an equity position behaves nothing like one. And it is heavily retail-driven, which makes sentiment swings sharper and reversals faster.

That combination is exactly why the fundamentals is worth getting right here specifically. Approaches that are merely helpful in a nine-to-five market become load-bearing in one that runs continuously and moves several times as fast.

It is also why automation beats attention. You cannot watch a 24/7 market; you can only decide in advance what would make you act, and arrange to be told when it happens. Everything below is built on that principle.

Never miss a move in the markets you follow

Set a price or percentage alert once and get a push notification the moment it triggers — free, with quiet hours so nothing wakes you at 3am.
