More coins vs better liquidity: picking an exchange for majors or long-tail alts
Gate.io lists 1,700+ coins at 3.8/5 liquidity; Binance lists 380+ at 4.9/5. The gap explains why catalog size and fill quality pull apart.
The exchange with the most coins is rarely the exchange with the deepest order books — and the numbers in our exchange data show exactly that split. Gate.io carries the widest catalog we track, at 1,700+ listed coins with a 3.8/5 liquidity rating. Binance carries far fewer, 380+ coins, but earns our highest liquidity rating at 4.9/5. If you mainly trade BTC, ETH and other majors in size, the depth side of that trade-off matters more than the coin count. If you are researching small-cap and newly listed tokens and trading in small size, breadth is the feature you actually need — but you pay for it in spreads and slippage.
What the two ratings actually say
A liquidity rating is not a volume headline or a popularity score. It is a summary of how easy it is to get filled near the quoted price: how much resting depth sits close to the mid-price, how wide the typical spread runs, and how much a normal-sized order moves the market. A 3.8/5 and a 4.9/5 are not a small difference in that context — they describe two different trading experiences. Note also that a venue-level rating summarises an entire catalog, and a 1,700-coin catalog includes a long tail of pairs that individually see very little activity. A 380-coin catalog can be curated more tightly, which is one reason its average depth reads higher.
Why a bigger catalog can mean thinner books
Liquidity is not spread evenly across listings; it clusters where trading interest clusters. Adding a pair does not automatically add market makers to it. Several structural reasons push breadth and depth in opposite directions:
- Market makers allocate capital and inventory to the pairs where flow is heaviest, so a long tail of low-interest tokens tends to sit on thin, wide books.
- Every additional listing is another risk and operations burden for the venue and its liquidity providers, which is why curation and breadth are usually a deliberate trade-off rather than an accident.
- On a thin pair, the quoted spread is wider and a modest order can walk the book several levels, so your effective entry or exit price is worse than the screen suggests.
- Thin books also gap: with fewer participants, price can jump between trades, which matters more for anyone using tight risk limits.
Pick by what you trade, not by coin count
- If your activity is concentrated in majors and position size is meaningful: prioritise the liquidity-heavy venue. Deep books mean less slippage per order and prices that hold up when you scale in or out.
- If your activity is scouting long-tail alts, new listings and niche tokens: prioritise the broad-catalog venue, but size positions to the book, use limit orders where possible, and check depth before you commit.
- If you do both: treat them as two jobs. Many traders keep a deep-book venue for majors and use a wide-catalog venue for discovery and small-size alt exposure, routing each order to whichever book can absorb it.
- Either way, verify the specific pair, not the exchange's overall reputation — depth varies enormously between a top pair and a listing three pages deep.
Which crypto exchange has the most coins?
In our exchange data, Gate.io has the widest catalog at 1,700+ listed coins, paired with a 3.8/5 liquidity rating. Breadth of listings is its defining characteristic versus larger rivals.
Which exchange has the best liquidity?
Binance holds our highest liquidity rating at 4.9/5, across a catalog of 380+ coins. That rating reflects depth and execution quality rather than the number of listings.
Is a bigger coin catalog better?
Not on its own. A larger catalog gives you access to more assets, including long-tail tokens you may not find elsewhere, but the average pair is typically thinner than on a curated venue. Whether that is better depends on whether you need access to those assets or need deep books in the assets you already trade.
Can I use both exchanges instead of choosing?
Yes, and it is a common approach: route major-pair orders to the deeper book and use the broad-catalog venue for discovery and small-size positions in long-tail tokens. The practical rule is to match each order's size to the depth of the specific pair you are trading.
What does a liquidity rating measure?
It summarises execution quality — resting depth near the mid-price, typical spread width and how much a normal-sized order moves the price — as opposed to trading volume alone. It is an informational measure, not a forecast of returns.
