How to arbitrage
Never done it before? One round takes a few minutes: buy a coin on one exchange, sell it where it pays more, bring the money back. Here it is step by step, worked out from today's rates.
0:00 / 0:48
Step 1 on Binance
Put USDT on Binance
Sign up on Binance, or any large exchange you trust, and deposit USDT. USDT is a stablecoin that tracks the dollar: 1 USDT is worth about 1 dollar.
WalletDepositUSDT
Step 2 on Binance
Buy BNB
Open the BNB/USDT spot market and buy with a market order. In the example: 1 BNB for 792.35 USDT, plus the trading fee.

RadarBinanceBNB1
Each search shows the ranking as it is right now. Rates move every few seconds, so act on a fresh one.
Step 4 on Pionex
Send the BNB there
On Pionex open Deposit, choose BNB and the BNB Smart Chain (BEP-20) network, and copy the address. On Binance open Withdraw, paste that address and pick the same network. It arrives in about 1 min.
Binance: WalletWithdrawBNB
Always choose the same network on both exchanges. Coins sent over the wrong network can be lost.
Step 5 on Pionex
Sell the BNB for USDT
On Pionex sell the BNB on the spot market. In the example 0.9995 BNB arrives after the withdrawal fee and sells for 791.56 USDT.
TradeSpotBNB/USDTMarketSell
Step 6 on Binance
Bring the USDT back and repeat
Withdraw the USDT to your Binance USDT deposit address, again on the same network. You are back where you started, with -0.3% more USDT. Run a fresh search before the next round.

The highest price is not always the best deal
Fees and slippage change the answer as the amount grows. Pick an amount and see what is left.
Your coins are on exchange A. Exchange B pays 0.42% more.
Is the transfer worth it? That depends on the amount.
B pays moreprice difference+0.42%+$105
Withdrawal from Aflat fee, about $5-0.02%−$5.00
Slippagethinner order book on B-0.07%−$17.50
Result vs selling on A+0.33%+$82.50
Worth it: about $82.50 more after all fees.
What the radar counts
Four things decide how much of the price reaches your account.
- Withdrawal fee
- Moving coins costs a flat fee. On a small sale it can cancel the whole difference.
- Now: 0.00012 BTC (about 10.30 USDT) to withdraw BTC from Binance
- Order book depth
- A large sale moves the price. The radar estimates the average price you would actually get.
- Now: selling 2 BTC on Gemini loses about 2.39% to slippage
- Deposit status
- Exchanges pause deposits for some coins. Those venues drop to the bottom, however well they pay.
- Paused now: BNB on MEXC
- Transfer time
- Every network has its own speed. The expected time is shown next to each option.
- Now: BTC 30 min, ETH 5 min, BNB 1 min, XRP 1 min
The gapminer.live index
A reference price for each coin: the median across exchanges with open deposits. It shows who pays above the market. It's not an offer: we don't trade.
- BTC85,844.70 USDTMedian of 28 exchanges with open deposits
- ETH2,705.89 USDTMedian of 28 exchanges with open deposits
- BNB792.34 USDTMedian of 21 exchanges with open deposits
- XRP1.5062 USDTMedian of 27 exchanges with open deposits
A median, so one exchange with a stale or odd price can't move it. Prices come from the exchanges' own market data and update every few seconds.
Questions
- Is it free?
- Your first 5 searches are free after signup. After that you buy a pack of searches; unused searches never expire. Some exchange links are affiliate links, and the ranking is always sorted by what you receive, never by what we earn.
- Does gapminer.live buy or sell crypto?
- No. We only compare rates. Every trade happens on the exchange you pick, and we never hold funds or ask for API keys.
- Why do I need an account?
- Every search is counted for a person, so the radar needs to know whose it is. We only ask for an email and a password, and the first searches are on us.
- Where do the rates come from?
- Straight from the exchanges: prices and order-book depth come from their public market data and refresh every few seconds. Withdrawal fees and deposit statuses are checked by our team. The radar shows when each price was last updated.
- What is the gapminer.live index?
- A reference price for each coin: the median across exchanges with open deposits. It shows whether an exchange pays above or below the market. Nobody buys or sells at it.
- Is this investment advice?
- No. The radar shows a calculation from current data. The decision to trade and its risks are yours.
