OHow to Buy OK
Every exchange we track that lists OK, what the buy costs, and what it costs to take OK with you afterwards.
2 of the exchanges we track list OK, and 2 of those accept fiat, so you can buy it without holding crypto first. The cheapest place to place the order is MEXC at $0.50 on a $1,000 market buy. OK has no market-cap listing, so nobody publishes a dollar price we could convert the withdrawal fee into — the cheapest exit we can see is 65,000,000 OK on MEXC over Solana, charged in the coin itself. Every exchange sends OK over Solana, so there is no network to get wrong. 1 of them has OK withdrawals paused right now — you can buy there, but you cannot take the coin with you until it reopens.

Where to buy OK
OK has no market-cap listing we can price it from, so the exit fee is shown in OK itself rather than in dollars — the amount each exchange deducts when you withdraw. It is still the number that decides where to buy, because it is flat: the smaller your purchase, the more of it the fee eats. The coins column is how many assets each exchange lists in total, from our own sync — not the figure CoinMarketCap prints.

Buying OK step by step
- Pick a venue from the table. For a coin this size the choice is usually short — 2 exchanges list OK at all, and the table already shows what you will pay to leave as well as to buy.
- Fund the account. 2 of those exchanges take fiat, 2 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 OK on the exchange is free but custodial. Moving it to a wallet that supports it costs one withdrawal fee — send a small test amount first, and match the network on both sides.
How to buy OK — FAQ
Where can I buy OK?
On 2 exchanges we track: MEXC, BitMart. The table above has each one with its trading fee, the payment methods it takes and what it charges to withdraw OK.
What is the cheapest way to buy OK?
We cannot put a dollar figure on it: OK has no market-cap listing, so there is no price to convert its withdrawal fee into. What we can compare is the two halves separately — the lowest trading fee is $0.50 per $1,000 at MEXC, and the cheapest withdrawal is 65,000,000 OK at MEXC over Solana. Work out which matters more from the size of your buy.
Can I buy OK with a credit card?
Indirectly, yes. 2 of the exchanges listing OK accept a card (MEXC, BitMart), but the card almost always buys a major asset — USDT, USDC, BTC — which you then swap for OK 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 OK?
Every exchange charges one, as a flat amount of OK per network rather than a percentage. We do not have a priced figure for all of the venues listing OK yet — the OK withdrawal fee page has whatever each exchange publishes.
Is it safe to leave OK 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. For a trading balance, staying put is reasonable; for a long hold, most people move.
A note on this page: OK is a ticker the exchanges below list and settle, but it has no CoinMarketCap listing, so there is no price, market cap or rank to show and no coin page for it elsewhere on this site. Tickers are not unique across exchanges either — confirm on the exchange itself that its OK is the asset you mean, and check the contract address before you send anything.
Exchange coverage for OK 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. 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.
