How to Buy IDEX
Every exchange we track that lists IDEX, what the buy costs, and what it costs to take IDEX with you afterwards.
15 of the exchanges we track list IDEX, and 14 of those accept fiat, so you can buy it without holding crypto first. The cheapest place to place the order is Ourbit at $0.00 on a $1,000 market buy. It is also the cheapest once the withdrawal fee is added — $0.09 to buy $1,000 of IDEX and move it to your own wallet. Every exchange sends IDEX over Ethereum (ERC20), so there is no network to get wrong. 2 of them have IDEX withdrawals paused right now — you can buy there, but you cannot take the coin with you until it reopens.

Where to buy IDEX
All-in cost is the trading fee on a $1,000 market buy plus the cheapest fee that exchange charges to withdraw IDEX. It is the number the exchange’s own “how to buy” page never shows you, and it reorders the table more often than not. The coins column is how many assets each exchange lists in total, from our own sync — not the figure CoinMarketCap prints.

Buying IDEX step by step
- Pick a venue from the table. For a coin this size the choice is usually short — 15 exchanges list IDEX at all, and the table already shows what you will pay to leave as well as to buy.
- Fund the account. 14 of those exchanges take fiat, 10 of them by card. Card is fastest and dearest; a bank transfer costs a fraction of it. Depositing a stablecoin you already hold is free on almost every exchange here.
- Place the order. A market order pays the taker fee in the table; a limit order that rests on the book pays the lower maker fee. On a thinly traded coin the spread costs more than either, so a limit order is worth the wait.
- Decide whether to move it. Leaving IDEX on the exchange is free but custodial. Moving it to a wallet that supports it costs one withdrawal fee, from $0.08760 — send a small test amount first, and match the network on both sides.
How to buy IDEX — FAQ
Where can I buy IDEX?
On 15 exchanges we track: MEXC, Binance, Bitget, Gate, Ourbit and 10 more. The table above has each one with its trading fee, the payment methods it takes and what it charges to withdraw IDEX.
What is the cheapest way to buy IDEX?
Ourbit, at $0.09 to buy $1,000 of IDEX and withdraw it — $0.00 in trading fee plus $0.08760 to move it out over Ethereum (ERC20). If you are leaving the coin on the exchange, only the first half applies and a different venue may win. Paying by card adds the card processor's charge on top of both, typically 1.8–4%.
Can I buy IDEX with a credit card?
Indirectly, yes. 10 of the exchanges listing IDEX accept a card, but the card almost always buys a major asset — USDT, USDC, BTC — which you then swap for IDEX on the same exchange. That means two fees: the card charge, then the trading fee in the table.
Do I have to pay a fee to withdraw IDEX?
Yes, and it is worth checking before you choose where to buy. It is a flat amount of IDEX, set by each exchange per network, so it does not scale with the size of your purchase — the cheapest in the table is $0.08760 on Ourbit. Our full IDEX withdrawal fee table compares every exchange and every network.
Is it safe to leave IDEX on the exchange?
It is a custody choice, not a safety switch. While the coin sits there the exchange holds the keys: convenient, recoverable if you lose your password, and dependent on the exchange staying solvent and keeping withdrawals open. Moving it to a wallet you control removes that dependency and costs one withdrawal fee — from $0.08760 for IDEX. For a trading balance, staying put is reasonable; for a long hold, most people move.
Exchange coverage for IDEX comes from each exchange’s own deposit and withdrawal endpoints (last sync 2026-08-29 00:53 UTC); trading fees are the published base tier, no volume discount applied (verified 2026-08-28). Exchanges we have a referral arrangement with appear first and are tagged as such — it changes no number in any row. Nothing here is investment advice; see our methodology.
