How to Buy BIAOEvery exchange we track that lists BIAO, what the buy costs, and what it costs to take BIAO with you afterwards.
2 of the exchanges we track list BIAO, 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. It is also the cheapest once the withdrawal fee is added — $0.50 to buy $1,000 of BIAO and move it to your own wallet. BIAO moves over 2 networks (BNB Smart Chain (BEP20), Ethereum (ERC20)) — pick the same one on the exchange withdrawal screen and in your wallet.
All-in cost is the trading fee on a $1,000 market buy plus the cheapest fee that exchange charges to withdraw BIAO. 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.

Showing 1–2 of 2 exchanges listing BIAO
On 2 exchanges we track: MEXC, Bitget. The table above has each one with its trading fee, the payment methods it takes and what it charges to withdraw BIAO.
MEXC, at $0.50 to buy $1,000 of BIAO and withdraw it — $0.50 in trading fee plus $0.00 to move it out over BNB Smart Chain (BEP20). 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%.
Indirectly, yes. 2 of the exchanges listing BIAO accept a card (MEXC, Bitget), but the card almost always buys a major asset — USDT, USDC, BTC — which you then swap for BIAO on the same exchange. That means two fees: the card charge, then the trading fee in the table.
Every exchange charges one, as a flat amount of BIAO per network rather than a percentage. We do not have a priced figure for all of the venues listing BIAO yet — the BIAO withdrawal fee page has whatever each exchange publishes.
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.
BIAO is issued on 2 networks and they are not interchangeable — BIAO sent over BNB Smart Chain (BEP20) will not arrive at an address on Ethereum (ERC20). BNB Smart Chain (BEP20) is the one most exchanges use (1 of them). Withdrawal fees differ per network too, sometimes by an order of magnitude, so the cheapest network is worth checking as well as the cheapest exchange.
Exchange coverage for BIAO 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.
