FHow to Buy Function (FBTC)
Every exchange we track that lists FBTC, what the buy costs, and what it costs to take FBTC with you afterwards.
None of the exchanges we track currently accepts FBTC deposits or withdrawals, so we have no venue to point you at. That usually means the token trades only on a decentralised exchange, or that it has been delisted.
Where to buy FBTC
No exchange we track currently lists FBTC.
Buying FBTC step by step
- Pick a venue from the table. For a coin this size the choice is usually short — 0 exchanges list FBTC at all, and the table already shows what you will pay to leave as well as to buy.
- Fund the account. None of them takes fiat for FBTC, so buy USDT with a card or bank transfer elsewhere and withdraw it in. 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 FBTC 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 FBTC — FAQ
Where can I buy Function (FBTC)?
Not on any exchange we track. None of them accepts FBTC deposits or withdrawals today, which usually means it trades only on a decentralised exchange or has been delisted. Treat any site claiming otherwise with suspicion.
What is the cheapest way to buy FBTC?
We cannot rank the exchanges on cost for FBTC 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 FBTC with a credit card?
None of the exchanges listing FBTC takes a card for it directly. The usual route is to buy USDT with a card on an exchange that does, withdraw it, and trade it for FBTC on one of the venues above. Budget for the card charge, the USDT withdrawal fee and the trade.
Do I have to pay a fee to withdraw FBTC?
Every exchange charges one, as a flat amount of FBTC per network rather than a percentage. We do not have a priced figure for all of the venues listing FBTC yet — the FBTC withdrawal fee page has whatever each exchange publishes.
Is it safe to leave FBTC 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 FBTC comes from each exchange’s own deposit and withdrawal endpoints (last sync —); 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.
