How to Buy Global Commercial Business (GCB)
Every exchange we track that lists GCB, what the buy costs, and what it costs to take GCB with you afterwards.
2 of the exchanges we track list GCB, 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 GCB and move it to your own wallet. Every exchange sends GCB over BNB Smart Chain (BEP20), so there is no network to get wrong.

Where to buy GCB
All-in cost is the trading fee on a $1,000 market buy plus the cheapest fee that exchange charges to withdraw GCB. 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 GCB step by step
- Pick a venue from the table. For a coin this size the choice is usually short — 2 exchanges list GCB 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 GCB 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 GCB — FAQ
Where can I buy Global Commercial Business (GCB)?
On 2 exchanges we track: MEXC, XT.COM. The table above has each one with its trading fee, the payment methods it takes and what it charges to withdraw GCB.
What is the cheapest way to buy GCB?
MEXC, at $0.50 to buy $1,000 of GCB 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%.
Can I buy GCB with a credit card?
Indirectly, yes. 2 of the exchanges listing GCB accept a card (MEXC, XT.COM), but the card almost always buys a major asset — USDT, USDC, BTC — which you then swap for GCB 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 GCB?
Every exchange charges one, as a flat amount of GCB per network rather than a percentage. We do not have a priced figure for all of the venues listing GCB yet — the GCB withdrawal fee page has whatever each exchange publishes.
Is it safe to leave GCB 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 GCB 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.
