How to Buy Diem
Every exchange we track that lists DIEM, what the buy costs, and what it costs to take DIEM with you afterwards.
2 of the exchanges we track list DIEM, and 2 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. But add the fee to move DIEM off the exchange and the order changes: MEXC comes out lowest at $0.84 all-in, against $6.76 on the cheapest trading fee. The withdrawal fee is flat, so the smaller your buy, the more it decides where you should buy. Every exchange sends DIEM over Base, so there is no network to get wrong.

Where to buy DIEM
All-in cost is the trading fee on a $1,000 market buy plus the cheapest fee that exchange charges to withdraw DIEM. 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 DIEM step by step
- Pick a venue from the table. For a coin this size the choice is usually short — 2 exchanges list DIEM 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, 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 DIEM on the exchange is free but custodial. Moving it to a wallet that supports it costs one withdrawal fee, from $0.3379 — send a small test amount first, and match the network on both sides.
How to buy DIEM — FAQ
Where can I buy Diem?
On 2 exchanges we track: MEXC, Ourbit. The table above has each one with its trading fee, the payment methods it takes and what it charges to withdraw DIEM.
What is the cheapest way to buy DIEM?
MEXC, at $0.84 to buy $1,000 of DIEM and withdraw it — $0.50 in trading fee plus $0.3379 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%.
Can I buy DIEM with a credit card?
Indirectly, yes. 1 of the exchanges listing DIEM accepts a card (MEXC), but the card almost always buys a major asset — USDT, USDC, BTC — which you then swap for DIEM 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 DIEM?
Yes, and it is worth checking before you choose where to buy. It is a flat amount of DIEM, set by each exchange per network, so it does not scale with the size of your purchase — the cheapest in the table is $0.3379 on MEXC. Our full DIEM withdrawal fee table compares every exchange and every network.
Is it safe to leave DIEM 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 — from $0.3379 for DIEM. For a trading balance, staying put is reasonable; for a long hold, most people move.
Exchange coverage for DIEM 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).
