OHow to Buy Optopia (OPAI)
Every exchange we track that lists OPAI, what the buy costs, and what it costs to take OPAI with you afterwards.
2 of the exchanges we track list OPAI, 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. Every exchange sends OPAI over Ethereum (ERC20), so there is no network to get wrong. 1 of them has OPAI withdrawals paused right now — you can buy there, but you cannot take the coin with you until it reopens.

Where to buy OPAI
All-in cost is the trading fee on a $1,000 market buy plus the cheapest fee that exchange charges to withdraw OPAI. 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 OPAI step by step
- Pick a venue from the table. For a coin this size the choice is usually short — 2 exchanges list OPAI 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 OPAI 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 OPAI — FAQ
Where can I buy Optopia (OPAI)?
On 2 exchanges we track: MEXC, KuCoin. The table above has each one with its trading fee, the payment methods it takes and what it charges to withdraw OPAI.
What is the cheapest way to buy OPAI?
We cannot rank the exchanges on cost for OPAI yet: the venues that list it have not published enough of their fee schedule for a like-for-like comparison. The withdrawal fees in the table are still exact.
Can I buy OPAI with a credit card?
Indirectly, yes. 2 of the exchanges listing OPAI accept a card (MEXC, KuCoin), but the card almost always buys a major asset — USDT, USDC, BTC — which you then swap for OPAI 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 OPAI?
Every exchange charges one, as a flat amount of OPAI per network rather than a percentage. We do not have a priced figure for all of the venues listing OPAI yet — the OPAI withdrawal fee page has whatever each exchange publishes.
Is it safe to leave OPAI 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.
Exchange coverage for OPAI 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.
