CHow to Buy CoinUp.io (CPX)
Every exchange we track that lists CPX, what the buy costs, and what it costs to take CPX with you afterwards.
CPX is thin on the ground: exactly one exchange we track lists it, MEXC. With a single venue there is nothing to compare on price, so the thing worth checking is whether withdrawals are open before you buy. The cheapest place to place the order is MEXC at $0.50 on a $1,000 market buy. CPX moves over 2 networks (BNB Smart Chain (BEP20), Ethereum (ERC20)) — pick the same one on the exchange withdrawal screen and in your wallet.

Where to buy CPX
All-in cost is the trading fee on a $1,000 market buy plus the cheapest fee that exchange charges to withdraw CPX. 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 CPX step by step
- Pick a venue from the table. For a coin this size the choice is usually short — 1 exchange lists CPX at all, and the table already shows what you will pay to leave as well as to buy.
- Fund the account. 1 of those exchanges takes fiat, 1 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 CPX 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 CPX — FAQ
Where can I buy CoinUp.io (CPX)?
On 1 exchange we track: MEXC. The table above has its trading fee, the payment methods it takes and what it charges to withdraw CPX.
What is the cheapest way to buy CPX?
We cannot rank the exchanges on cost for CPX 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 CPX with a credit card?
Indirectly, yes. 1 of the exchanges listing CPX accepts a card (MEXC), but the card almost always buys a major asset — USDT, USDC, BTC — which you then swap for CPX 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 CPX?
Every exchange charges one, as a flat amount of CPX per network rather than a percentage. We do not have a priced figure for all of the venues listing CPX yet — the CPX withdrawal fee page has whatever each exchange publishes.
Is it safe to leave CPX 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.
Which network should I use for CPX?
CPX is issued on 2 networks and they are not interchangeable — CPX sent over BNB Smart Chain (BEP20) will not arrive at an address on Ethereum (ERC20). BNB Smart Chain (BEP20) 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.
Exchange coverage for CPX 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.
