Every exchange we track that lists BIOS, what the buy costs, and what it costs to take BIOS with you afterwards.
2 of the exchanges we track list BIOS, and 2 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. BIOS 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 30 BIOS on Ourbit over Base, charged in the coin itself. BIOS moves over 2 networks (Base, Solana) — pick the same one on the exchange withdrawal screen and in your wallet.
BIOS has no market-cap listing we can price it from, so the exit fee is shown in BIOS 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.

Showing 1–2 of 2 exchanges listing BIOS
On 2 exchanges we track: MEXC, Ourbit. The table above has each one with its trading fee, the payment methods it takes and what it charges to withdraw BIOS.
We cannot put a dollar figure on it: BIOS 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 $0.00 per $1,000 at Ourbit, and the cheapest withdrawal is 30 BIOS at Ourbit over Base. Work out which matters more from the size of your buy.
Indirectly, yes. 1 of the exchanges listing BIOS accepts a card (MEXC), but the card almost always buys a major asset — USDT, USDC, BTC — which you then swap for BIOS 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 BIOS per network rather than a percentage. We do not have a priced figure for all of the venues listing BIOS yet — the BIOS 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.
BIOS is issued on 2 networks and they are not interchangeable — BIOS sent over Base will not arrive at an address on Solana. Base 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.
A note on this page: BIOS 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 BIOS is the asset you mean, and check the contract address before you send anything.
Exchange coverage for BIOS 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.
