Key takeaways (TL;DR):
- Market cap is not a "company valuation"; it is price × circulating supply. It only counts coins already trading, not the total the project may eventually issue. To see future supply, use FDV (fully diluted valuation).
- The gap between FDV and market cap is future dilution pressure. In the 7 November 2026 snapshot, HYPE's FDV was 3.97× its circulating market cap, SUI 2.42× and XRP 1.57×, while BTC and ETH were about 1.00×.
- Volume is turnover, not money flowing in. The same dollars and coins can trade repeatedly, inflating volume while net inflows stay near zero. For liquidity, look at 24-hour volume ÷ circulating market cap.
- Turnover must be compared within the same asset class. On the same day, BTC was about 1.81%, ETH 3.55%, BNB 0.73% and USDT 25.14% — stablecoins are trading media and cannot be judged by the same yardstick.
- A low unit price does not mean cheap. SUI trades below $1 but has a circulating market cap of about $3.6 billion; BTC trades near $76,000 with a market cap of about $1.53 trillion. The unit price is just a result of supply.
- Market cap rank is not a safety rank. On the same day, ETH was about 54.6% below its all-time high, XRP about 68.0% and SUI about 83.7%. Rank measures size, not downside protection.
Market cap, trading volume and price change answer three different questions: how big the market currently prices this asset, how much of it changes hands each day, and how its price has moved recently. None of them tells you whether to buy, but together they help you screen out obvious mismatches.
The problem is that beginners misread exactly these three numbers: treating market cap as a valuation, volume as inflows, and a low unit price as cheap. This guide uses a live CoinGecko snapshot from 7 November 2026 to break down six metrics, then gives a reading order you can follow directly. If you have not bought crypto before, start with how to buy crypto as a beginner.

The short answer: what each number actually answers
Market cap answers "how big," volume answers "how active," and price change answers "how it has moved." None of them answers "is it worth buying."
| Metric | The question it answers | What it cannot answer |
|---|---|---|
| Circulating market cap | How the market prices the coins currently in circulation | What the whole project is worth, or future dilution |
| FDV (fully diluted valuation) | The value if all future supply is counted | When those coins unlock, or whether they will actually trade |
| 24-hour volume | How much value changed hands in the past day | How much net money flowed in, or where the price goes next |
| Turnover ratio | How active volume is relative to market cap | Whether the volume is real demand or wash trading |
| Multi-period price change | Price movement across different time windows | Whether the trend will continue |
| ATH drawdown | How far the price is below its all-time high | Whether it is "cheap" now |
The main purpose of this table is to stop you from treating one metric as a conclusion. "Top 10 by market cap" only describes size, not safety; "up 50% in 24 hours" only describes the past day, not tomorrow.
One line: metrics are for eliminating options, not for predicting prices. Use them to filter out obvious mismatches, then study the project, token economics and risks.
Metric 1: circulating market cap — price × circulating supply
Circulating market cap = current price × circulating supply. It counts only coins already in circulation and available to trade, not locked tokens, team allocations or reserves.
Using the 7 November 2026 CoinGecko snapshot1:
| Coin | Price | Circulating market cap | Circulating supply | Max supply |
|---|---|---|---|---|
| BTC | $76,029 | $1.53T | 20.108M | 21M |
| ETH | $2,246 | $274.5B | 122.2M | No cap |
| BNB | $695 | $91.4B | 131.5M | 200M |
| XRP | $1.17 | $74.2B | 63.52B | 100B |
| HYPE | $79.55 | $19.1B | 239.4M | 1B |
| SUI | $0.87 | $3.60B | 4.139B | 10B |
What matters most is not the size of the numbers but the gap between circulating and maximum supply:
- BTC has about 95.8% of its max supply in circulation, so future issuance is small.
- XRP has about 63.5% circulating, leaving roughly 36.5% not yet in circulation.
- SUI has about 41.4% circulating; HYPE only about 23.9%.
The lower the circulating ratio, the easier it is for a "small float plus high unit price" to support a market cap — and the more potential supply can hit the market when unlocks occur. That is why circulating market cap alone is not enough; you also need FDV.
Metric 2: FDV — how much supply is still coming
FDV (fully diluted valuation) = current price × future total supply. It answers: if every coin that could enter circulation were counted, how would the market price this project today?
| Coin | Circulating market cap | FDV | FDV ÷ market cap | Meaning |
|---|---|---|---|---|
| BTC | $1.53T | $1.53T | 1.00 | Almost fully circulating |
| ETH | $274.5B | $274.5B | 1.00 | No fixed cap; based on current supply |
| BNB | $91.4B | $91.4B | 1.00 | See the methodology note below |
| XRP | $74.2B | $116.8B | 1.57 | About 36.5% not circulating |
| SUI | $3.60B | $8.70B | 2.42 | About 58.6% not circulating |
| HYPE | $19.1B | $75.7B | 3.97 | About 76.1% not circulating |
Read the last column:
- Near 1.00: little future supply, low dilution pressure.
- 1.5–2×: a meaningful share is not circulating; watch the unlock schedule.
- Above 3×: only a small part of the fully diluted value is circulating, so future dilution pressure is significant.
⚠️ FDV definitions are not uniform. Take BNB: CoinGecko shows FDV and market cap both around $91.4 billion because it uses total supply of 131.5 million. If you use the maximum supply of 200 million, FDV would be about $139 billion and FDV/market cap about 1.52×1. Whenever you see FDV, check whether it multiplies total supply or max supply — different sources can produce different numbers. This is also one reason the same coin shows different figures on different sites; see the site's CoinGecko vs CoinMarketCap comparison.
A high FDV does not mean a project is bad. It states a structural fact: more tokens will enter circulation in the future. Whether they are sold, and whether real demand can absorb them, are separate questions.
Metric 3: 24-hour volume — turnover, not inflows
Volume is the total value of all trades in the past 24 hours. It measures turnover, not net inflows.
The simplest example: you buy 1 BTC for $76,000 from a seller. The trade's volume is $76,000, but net inflow is 0 — one person bought, one sold; the money and the coin simply changed hands. If that same BTC changes hands 10 times in a day, volume becomes $760,000, but there is still only that one BTC being traded repeatedly.
So:
- High volume ≠ a lot of new money entering. It only means active turnover.
- High volume ≠ the price will rise. High-volume sell-offs are common.
- Low volume ≠ nobody wants it. It may mean holders are not selling, the float is small, or exchange depth is thin.
The more useful question is: how many assets, on how many exchanges, produced this volume? If volume is concentrated on one exchange, or the price spikes without a matching rise in volume, look closer.
Metric 4: turnover ratio — volume divided by market cap
Turnover ratio = 24-hour volume ÷ circulating market cap. It standardises volume so you can compare coins of different sizes.
The 7 November 2026 snapshot1:
| Coin | 24h volume | Circulating market cap | Turnover |
|---|---|---|---|
| BTC | $27.66B | $1.53T | 1.81% |
| ETH | $9.75B | $274.5B | 3.55% |
| BNB | $0.665B | $91.4B | 0.73% |
| XRP | $2.11B | $74.2B | 2.84% |
| HYPE | $0.867B | $19.1B | 4.55% |
| SUI | $0.274B | $3.60B | 7.60% |
| USDT | $44.47B | $176.9B | 25.14% |
There is no "normal" turnover ratio, only same-class comparison:
- BTC at 1.81%: large cap, low turnover — relatively stable holdings, or much of the trading happens in derivatives rather than spot.
- ETH at 3.55%: more active than BTC but the same order of magnitude.
- BNB at 0.73%: low turnover, possibly related to holder structure and the exchange ecosystem.
- USDT at 25.14%: a stablecoin is trading media; the same USDT is reused all day, so its turnover is naturally high and cannot be compared directly with an equity-like asset.
One line: turnover is relative activity, not a quality score. High turnover can be real demand or wash trading; low turnover can be long-term holding or an illiquid market. Judge it together with where the volume sits and how deep the order book is.
Metric 5: multi-period price change — 24 hours is one slice
A 24-hour price change describes only the past day's rolling move. It is neither a trend nor a fixed reference point. Different data sources define the start of "24 hours" differently: some use a rolling window, some reset at UTC midnight, some use an exchange's local time zone. That is why the same coin can show different numbers in two apps — not because one is wrong, but because the windows differ.
The right way to read price change is to put several periods side by side:
| Coin | 1h | 24h | 7d | 30d | From ATH |
|---|---|---|---|---|---|
| BTC | +0.01% | -0.17% | -1.74% | -8.54% | -39.70% |
| ETH | +0.03% | +0.20% | +0.12% | -12.89% | -54.59% |
| XRP | — | -3.87% | -7.06% | -18.10% | -67.99% |
| HYPE | +0.45% | +2.01% | -11.28% | -9.82% | -18.79% |
| SUI | -0.72% | +0.63% | -3.94% | -23.16% | -83.73% |
This table shows things a single 24-hour number hides:
- HYPE: +2.01% in 24h but -11.28% in 7d. It is bouncing today but still falling over the week.
- SUI: +0.63% in 24h but -23.16% in 30d and -83.73% from ATH. One day's bounce is not a trend reversal.
- ETH: +0.20% in 24h and +0.12% in 7d, but -12.89% in 30d. Range-bound short term, still retracing on the month.
One line: 24 hours is noise; 7 and 30 days are the outline of the trend. Use 1h/24h for short-term context, but judge position with 7d/30d and ATH drawdown.
Metric 6: ATH drawdown — how far below the peak
ATH drawdown measures how far the current price is below its all-time high. It answers "where is this coin in its history," not "is it cheap now."
The 7 November 2026 snapshot1:
- BTC: about -39.7% from ATH
- ETH: about -54.6%
- XRP: about -68.0%
- HYPE: about -18.8%
- SUI: about -83.7%
A large drawdown does not mean cheap. A coin 80% below its high may be down because the whole market fell, or because fundamentals deteriorated, tokens kept unlocking, or the narrative disappeared. Drawdown is a position, not a valuation.
A small drawdown does not mean safe either. HYPE is only about 18.8% below its high, but its FDV is 3.97× its market cap, so future dilution pressure remains.
One line: ATH drawdown tells you how far it fell; FDV and fundamentals tell you why and whether it may fall further. Read them together so you do not mistake "fell a lot" for "worth buying."
A low unit price does not mean cheap
The unit price is just market cap divided by supply; it has no direct relationship with upside. This is the most common beginner trap, because "0.87" looks cheaper than "76,029" in an exchange list.
Using the same snapshot:
- SUI: unit price about $0.87, circulating market cap about $3.6 billion, FDV about $8.7 billion.
- BTC: unit price about $76,029, circulating market cap about $1.53 trillion, FDV about $1.53 trillion.
SUI's unit price is low because its supply is measured in billions; BTC's is high because its supply is measured in tens of millions. A low unit price does not mean "more room to grow"; it means each token represents a smaller share.
A purely hypothetical example: a token with 1 trillion total supply at $0.0001 per token has a $100 million market cap. It looks like "you can buy a lot for a few cents," but its market cap may be higher than many coins priced at tens of dollars. When comparing two coins, compare market cap and FDV first, unit price last. If you are deciding how much to start with, see the minimum amount needed to buy crypto.
Market cap rank is not a safety rank
Market cap rank sorts by circulating market cap, not by safety, liquidity or upside. A high rank means the market currently prices it larger, not that it cannot fall.
In the 7 November 2026 snapshot1:
- ETH's market cap was about $274.5 billion, about -54.6% from its ATH.
- XRP's market cap was about $74.2 billion, about -68.0% from its ATH.
- SUI's market cap was about $3.6 billion, about -83.7% from its ATH.
Large caps usually have better liquidity and longer histories, but "large" does not mean "stable"; small caps are more volatile, shallower and easier to manipulate. Use rank to understand position in the market, not as a substitute for risk assessment.
One line: rank answers "how big"; risk assessment answers "can I stomach it." They are not interchangeable.
A six-step reading order for beginners
Do not start with the price and the 24-hour change. Follow this order to screen out most obvious mismatches in a few minutes:
- Check market cap rank and circulating market cap. Get a sense of its size so you do not mistake a small cap for a mainstream asset.
- Check FDV ÷ circulating market cap. Near 1 means little dilution; above 2 means look at the unlock schedule; above 3 means be especially careful about future supply.
- Check 24-hour volume ÷ circulating market cap. Too low means weak liquidity and potentially large slippage; too high also warrants a check for wash trading.
- Check where the volume sits. Heavy volume on one small exchange with almost nothing elsewhere is a warning.
- Check 1h / 24h / 7d / 30d changes. A short-term bounce inside a medium-term decline is a different state from a medium-term uptrend with a short-term pullback.
- Check ATH drawdown and the unlock schedule. Drawdown tells you position; unlocks tell you how much new supply may arrive.
After these six steps you can answer: how big it is, whether future supply will dilute it, whether liquidity is sufficient, whether it is rising or falling recently, and how far below its high it sits. None of these is a buy reason, but they eliminate many "looks cheap but is illiquid or heavily diluted" candidates. For the actual order types — limit, market and stop — see the Binance spot trading guide.
Five red flags
- Low float + high FDV. A small circulating supply with an FDV several times the market cap means a lot of tokens will enter circulation later. HYPE at 3.97× and SUI at 2.42× are structural examples, not verdicts — but you must check the unlock pace and whether demand can absorb it.
- Very low volume/market cap combined with a sudden price spike. A small amount of money may be pushing the price in a shallow pool; real liquidity may not support your entry or exit.
- Volume concentrated on a single exchange. The data may be wash traded, or liquidity may be thin; another exchange may show a completely different picture.
- A large unlock or team allocation entering circulation soon. New supply adds sell pressure, especially when demand is not growing.
- A high rank but weak on-chain activity and fee revenue. Rank is price × circulating supply; it does not prove real usage. Check on-chain data, not just the market page.
These five signals do not mean "it will fall." They mean "ask one more question." Their job is to make you stop and check, not to make the decision for you.

FAQ
What is the difference between market cap and fully diluted valuation?
Market cap is price multiplied by circulating supply — only coins already trading. Fully diluted valuation (FDV) also counts supply that may enter circulation in the future. A much higher FDV means more tokens will be unlocked or issued, creating dilution pressure. The wider the gap, the more you need to check the unlock schedule.
Does high volume mean a lot of money is flowing in?
No. Volume counts turnover on both sides of every trade. The same dollars and the same coins can change hands repeatedly, inflating volume while net inflows stay close to zero. To judge liquidity, use 24-hour volume divided by circulating market cap, and check whether volume is spread across several credible exchanges.
Why does the 24-hour price change differ between apps?
Because the starting point of the 24-hour window differs. Some sources use a rolling 24 hours, some reset at UTC midnight, and some use an exchange's local time zone; price aggregation also differs. Short-term numbers naturally diverge, so read 1-hour, 24-hour, 7-day and 30-day changes together instead of fixating on one number.
Are low-priced coins more likely to rise?
No. The unit price is just market cap divided by supply; it says nothing about upside. A $0.001 coin can have a $10 billion market cap, and a $76,000 coin can have a $1.5 trillion market cap. Compare market cap, FDV, liquidity and fundamentals — not which unit price looks cheaper.
Are large-cap coins by market cap safe?
Rank only measures market cap, not safety. In the 7 November 2026 snapshot, ETH was about 54.6% below its all-time high and XRP about 68.0% below; the smaller-cap SUI was about 83.7% below. Large caps usually have better liquidity and consensus, but their prices can still fall sharply; small caps tend to be more volatile and easier to manipulate.
What is a normal turnover ratio?
There is no universal number. In the 7 November 2026 snapshot, BTC's 24-hour volume was about 1.81% of its circulating market cap, ETH about 3.55%, BNB about 0.73% and USDT about 25.14%. Stablecoins are trading media and naturally turn over faster, so only compare within the same asset class.
Is market cap, volume and price change enough to evaluate a coin?
Not enough. They answer how big, how active and how it has moved recently. They do not answer whether the project has real demand, whether token unlocks will add supply, or whether the contract is safe. Use them to screen out obvious mismatches, not as a standalone buy signal.
Verification notes
All prices, market caps, FDVs, volumes, supply figures, price changes and ATH drawdowns in this article come from the CoinGecko API /coins/markets endpoint, queried on 7 November 20261. These numbers change continuously; the figures here are a same-day snapshot used to explain the concepts, not a recommendation or price forecast for any coin. FDV supply definitions can differ between data sources; the BNB example is explained separately, and the CoinGecko versus CoinMarketCap methodology differences are covered in the site's comparison2.
This is not investment advice. Market cap, volume and price change are descriptive metrics and cannot predict prices; small caps carry higher liquidity, manipulation and delisting risks. Before trading, confirm official entry points, control position size, and never use borrowed money or your entire savings.
