The short answer
A crypto rating is somebody's judgment about a crypto asset, produced by a method they publish, and stamped with the date they produced it.
That is the whole definition. It has three working parts, and every useful question you can ask about a rating is really a question about one of them.
Somebody's judgment. A rating is a considered opinion. It is not a measurement of the asset the way a price is a measurement of what the last buyer paid.
Produced by a method they publish. This is what separates a rating from a hunch. If nobody will tell you how the number was reached, you are reading a hunch with a number printed on it.
On a date. A rating describes what the method found when it looked. It was produced at a moment, and the moment is part of the claim.
Everything below is those three sentences with the detail filled in.
What a rating is made of
Most crypto ratings, ours included, have four pieces on the page.
A framework. The written rules. Which things about a crypto asset get looked at, how much each one counts, and what disqualifies an asset outright. Ours is published at https://cryptograde.ai/framework and you can read it without an account.
A score. A number on a fixed scale, produced by running the asset through that framework. A score is absolute: it says how this crypto asset did against the rules, and it does not move just because some other token moved.
A grade. A short label that summarizes the score and the screens together. Ours are the letters A, B, C and F, quoted directly from our own published record rather than worked out by hand.
A date. When the assessment was produced. A rating without a date is not a rating, because you cannot tell whether you are reading this week's view or last spring's.
Some providers also publish a rank, which is a different thing again, and the next section is about why.
Score and rank answer different questions
This is the single most common confusion for someone new to crypto ratings and rankings, and it is worth thirty seconds.
A score is a number about one crypto asset on its own. Nothing another token does can change it. If an asset scores the same today as it did yesterday, our assessment of that asset did not move.
A rank is a position in a list. It is relative by construction: it describes where an asset sits compared to everything else being ranked at that moment. An asset's rank can move while its score sits perfectly still, because the things around it moved instead.
So "it went up five places" and "it scored better" are two different pieces of news, and only one of them is about the asset you are actually asking about. When you read a crypto ranking, check which number you are looking at. (There is more to say about what a rank change does and does not mean, and we will say it in a piece of its own.)
Where the number comes from
Here is our version, because it is the one we can describe first hand.
CryptoGrade uses AI to screen tens of thousands of cryptocurrencies as the input universe. The 200 crypto assets we publish ratings on are drawn from that broader set, ordered by our own score, highest to lowest.
Each of those assets is then run against the published framework: weighted dimensions that score how the asset is built and how it is used, plus pass or fail screens that sit on top of the score and can override it. That second half is why a letter grade is not simply a cutoff applied to a number, and it is worth its own explainer, which is the next thing this lane will write.
The part that matters most for trusting any of it: every score we publish records the version of the rules it was produced under, the identity of the model that produced it, and a basis label describing what the assessment rests on. That is the answer to the reasonable question a newcomer asks, which is "how do I know this isn't just made up."
Four things a crypto rating is not
It is not a price prediction. No part of a crypto grading framework, ours included, encodes a view on what a token will be worth next month. Scoring how an asset is built is a different exercise from forecasting what people will pay for it, and a provider who mixes the two is selling you the second thing wearing the first thing's clothes.
It is not a promise about the future. A rating describes what a method found when it looked. A high grade means the asset did well against a set of written rules on a date. It does not mean nothing can go wrong, and no honest rating provider will tell you otherwise. Crypto assets can lose value, quickly and completely, at every grade on the scale.
It is not advice about your situation. A rating is published to everyone who visits the page. It knows nothing about your finances, your timeline, your tax position or what else you hold, so it cannot be a recommendation to you specifically, and we do not write it as one. We publish investment research. What you do with it is yours to decide, ideally with a licensed professional who knows your circumstances.
It is not permanent. Grades change. Ours do. A rating is a dated statement, and the honest way to read one is as of its date rather than as a standing fact about the asset.
What the letter actually tells you
A letter grade is a compact summary, and compression always loses something. Here is what ours carries and what it does not.
It carries: how the asset did against our published framework, summarized into one label, quoted from our record rather than derived.
It does not carry: why you personally should care, what the asset will do next, or a ranking of how bad the worst cases are. An asset without a rank is not therefore the bottom of a list; it is an asset that is not in the ranked list, which is a different statement.
If you want the detail behind a letter, the letter is the doorway and not the answer. On our site each crypto asset has its own page with our research view on it, and that is where the reasoning lives.
How to use one without getting misled
Three habits, and they work on any crypto ratings provider, not only on us.
Read the date first. Before the number. If you cannot find one, stop reading.
Check what the number is a number of. A score, a rank and a price are three different measurements and they are frequently printed next to each other.
Ask whether the method is published. Not summarized. Published, in enough detail that you could argue with it. A framework you can disagree with is worth more than a number you cannot check.
What ours looks like, and what a free account changes
Anyone can visit https://cryptograde.ai and see our top 10 crypto assets by our own score. A free account opens the full published set of 200, ordered the same way, so you can look up a coin you actually hold rather than only the ones at the top.
The concrete thing the free account gets you beyond that: Alerts. You pick the crypto assets you care about and we tell you when the grade on one of them changes, instead of you remembering to come back and check. It is at https://cryptograde.ai/alerts and it costs nothing.
That is a good first use of a rating, and a better one than reading a leaderboard. Look up one asset you already own or have been curious about, read what our research says about it, and see whether it lines up with why you were interested in the first place. Check the grade on a coin you own.
