KuCoin
BigONEIn short: the difference
First in the pair, KuCoin, is an exchange that covers several jobs at once. On the market since 2017, jurisdiction: Seychelles, its own KCS token.
Second in the pair, BigONE, is a venue that doubles as a toolkit. On the market since 2017, jurisdiction: Seychelles, its own ONE token.
What KuCoin gives you
Compared with an ecosystem, KuCoin leans on its own strengths: The venue known for its trading bots: grid, DCA and arbitrage bots are configured right in the interface, with no third-party service. Alongside that, spot across eight hundred-plus pairs, perpetual futures, P2P, savings and staking under Earn, Spotlight launches and copy trading. Nineteen networks for USDT withdrawals.
Strong sides: built-in trading bots, 800+ spot pairs, 19 withdrawal networks, a broad P2P.
What BigONE gives you
The rival’s service list is wide, yet BigONE wins on other things: One of the older venues in this comparison: running since 2017, with a team that came out of the Yunbi exchange. It carries around nine hundred spot pairs and a hundred perpetual contracts, each publishing its funding rate, accrual interval and mark price. There is margin, leveraged tokens, staking and its own ONE token for fee discounts. Data is fully open, including the size resting at the best quote.
Strong sides: ~900 pairs and 100 contracts, best quotes with sizes, an open network directory with withdrawal fees, the ONE token for discounts.
What decides it
- Native tokens. KuCoin has KCS, BigONE has ONE: holders usually get fee discounts and access to launches.
- Strengths side by side. KuCoin: built-in trading bots, 800+ spot pairs, 19 withdrawal networks, a broad P2P; BigONE: ~900 pairs and 100 contracts, best quotes with sizes, an open network directory with withdrawal fees, the ONE token for discounts.
- Which job. KuCoin is for anyone who wants to automate trading without writing code, while BigONE is as an additional venue in spot routes and funding.
- Worth remembering. KuCoin: USDT withdrawals cost more than on neighbouring venues — compare networks before moving. BigONE: the top of the book is thin: on major coins the best price often holds only a hundred dollars or two.
Which one fits you
KuCoin — for anyone who wants to automate trading without writing code.
BigONE — as an additional venue in spot routes and funding.
What people ask most
KuCoin: How many coins are here? More than eight hundred spot pairs — KuCoin sits comfortably in the top five by listing, and many coins got their first serious book here.
KuCoin: How do the built-in bots work? The grid bot earns on swings inside a set range, DCA averages the entry, the arbitrage bot captures the gap between spot and futures. All configured with a mouse, no code and no third-party services.
KuCoin: What is KCS? The exchange own token. It discounts fees and pays daily distributions from part of the venue fee income — the latter is uncommon among exchange tokens.
BigONE: Does BigONE take part in your arbitrage sections? Yes, all of them. The exchange serves best quotes together with their sizes, so we can compute both the spread and the ceiling it fills at — which matters especially on a venue like this.
BigONE: Is the transfer status visible for BigONE? Yes, in full. The venue publishes networks, deposit and withdrawal statuses and the fee per chain, so its routes carry the ordinary transfer badge and the fee is subtracted from the net spread straight away.
BigONE: Why are spreads on BigONE often large? Because the top of the book is thin: the size at the best price is often a hundred dollars or two. The percentage on screen is real, but it fills only for that much. Use the «depth» button before trading.
Both at once
Nothing stops you from opening an account on both: it is free, and a pair of venues almost always beats any single one on price. It makes sense to split the jobs: spot and earn on one, bots and launches on the other. Balances are pre-funded, so no transfer is needed at the moment of a trade.
Live numbers
Everything in the table above is recomputed together with the rest of the site — pairs, contracts, P2P, networks and the withdrawal fee. KuCoin and BigONE can be compared on facts rather than promises.
