How to Buy COMMONEvery exchange we track that lists COMMON, what the buy costs, and what it costs to take COMMON with you afterwards.
18 of the exchanges we track list COMMON, and 17 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. It is also the cheapest once the withdrawal fee is added — $0.00 to buy $1,000 of COMMON and move it to your own wallet. Every exchange sends COMMON over Base, so there is no network to get wrong. 5 of them have COMMON withdrawals paused right now — you can buy there, but you cannot take the coin with you until it reopens.
All-in cost is the trading fee on a $1,000 market buy plus the cheapest fee that exchange charges to withdraw COMMON. 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 1–18 of 18 exchanges listing COMMON
On 18 exchanges we track: MEXC, Bitget, Gate, Ourbit, Toobit and 13 more. The table above has each one with its trading fee, the payment methods it takes and what it charges to withdraw COMMON.
Ourbit, at $0.00 to buy $1,000 of COMMON and withdraw it — $0.00 in trading fee plus $0.0002616 to move it out over Base. 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. 11 of the exchanges listing COMMON accept a card, but the card almost always buys a major asset — USDT, USDC, BTC — which you then swap for COMMON on the same exchange. That means two fees: the card charge, then the trading fee in the table.
Yes, and it is worth checking before you choose where to buy. It is a flat amount of COMMON, set by each exchange per network, so it does not scale with the size of your purchase — the cheapest in the table is $0.0002616 on Ourbit. Our full COMMON withdrawal fee table compares every exchange and every network.
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 — from $0.0002616 for COMMON. For a trading balance, staying put is reasonable; for a long hold, most people move.
Exchange coverage for COMMON 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.
