How to Buy Changer (CNG)Every exchange we track that lists CNG, what the buy costs, and what it costs to take CNG with you afterwards.
2 of the exchanges we track list CNG, 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 — $3.90 to buy $1,000 of CNG and move it to your own wallet. Every exchange sends CNG over Ethereum (ERC20), so there is no network to get wrong. 1 of them has CNG 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 CNG. 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 CNG
On 2 exchanges we track: MEXC, OrangeX. The table above has each one with its trading fee, the payment methods it takes and what it charges to withdraw CNG.
MEXC, at $3.90 to buy $1,000 of CNG and withdraw it — $0.50 in trading fee plus $3.40 to move it out over Ethereum (ERC20). 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 CNG accept a card (MEXC, OrangeX), but the card almost always buys a major asset — USDT, USDC, BTC — which you then swap for CNG 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 CNG, set by each exchange per network, so it does not scale with the size of your purchase — the cheapest in the table is $3.40 on MEXC. Our full CNG 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 $3.40 for CNG. For a trading balance, staying put is reasonable; for a long hold, most people move.
Exchange coverage for CNG 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.
