How to read a coin page without fooling yourself

Market cap, supply, volume and distance from the high — what each number honestly tells you, and the far longer list of things none of them tell you.

Every coin page on every site, including ours, shows roughly the same handful of numbers. They are genuinely useful, and they are routinely read to mean things they do not mean. Here is what each one is actually measuring.

Price on its own tells you nothing. Not whether something is cheap, not whether it is expensive, not how much room it has to grow. A coin at $0.0001 is not "early" and a coin at $60,000 is not "too late" — the price is simply the total value divided by however many units the designers chose to create. A project can pick any number of units it likes, and many pick a very large one precisely because a low unit price feels attainable. Comparing two coins by unit price is comparing nothing at all.

Market capitalisation is price multiplied by circulating supply. It is the closest thing to a size measurement, and it is the number to compare across coins rather than price. Two important caveats travel with it. First, it is not money that has been invested — it is the last traded price applied to every unit in existence, and most of those units have not traded anywhere near it. Second, "circulating" is an estimate, and a generous one on projects where a large share of the supply sits with the team, a foundation, or early investors under lock-ups that will eventually end.

Fully diluted valuation applies today's price to every unit that will ever exist. The gap between market cap and FDV is a schedule of future selling pressure. When FDV is several times market cap, most of the supply has not been released yet, and holders are competing with a stream of new units arriving on a timetable set by someone else. That is not automatically bad — it may be paying for development, validators, or liquidity. But a coin whose FDV is ten times its market cap has a very different shape from one where the two are nearly equal, and no other number on the page will show you that.

Supply caps mean less than they are made to mean. A fixed maximum is a real property of a protocol and it is also, for most tokens, just a parameter in a document. What matters is who can change it, how much is already issued, how much is being issued per year, and whether anyone is destroying units. "Deflationary" as a marketing word usually describes a burn small enough to be invisible next to the issuance.

Volume measures activity, not interest, and it is the easiest number to fake. Trading volume on venues with no external accountability is inflated as a matter of routine, because ranking and listing decisions are made on it. Volume relative to market cap is the more informative reading: consistently thin volume against a large cap means the price is being set by very few trades, which is a liquidity fact with direct consequences the moment you try to leave. That is a separate question worth its own guide — can you actually sell it covers it.

Distance from the all-time high is a fact about history, not a discount. "Down 90% from its high" is often presented as an opportunity. It equally often describes a project that people have finished with. The high was a price at which trading happened once; it establishes nothing about whether that price will exist again, and thousands of coins have never come near theirs. In the other direction, a coin at a new high is not therefore overpriced. Neither reading is available from the number.

Percentage moves need a denominator before they mean anything. A 40% daily move on a large, liquid asset is a genuine event. The same move on something with a few thousand dollars of daily volume can be one person buying. Always check the size of the thing before reacting to the size of the move.

What none of these numbers contain. Who controls the code and whether they can change it. Whether the tokens can be frozen, and by whom. How concentrated ownership is. Whether the network has users or only holders. Whether the contract has been audited, and by whom. Whether the team is identifiable. Whether the thing being built is needed. Market data cannot answer any of that, and it is where essentially all of the outcome lives.

How to use the numbers honestly. Treat them as a filter, not a verdict. They are excellent for ruling things out — a coin whose FDV dwarfs its market cap, whose volume is thin, and whose supply concentration is unexplained has told you something real. They cannot tell you what is worth owning, and any page implying otherwise is selling something. Ours shows the data, says where it came from, and stops there deliberately.
