Where to buy BAD
All-in cost is the trading fee on a $1,000 market buy plus the cheapest fee that exchange charges to withdraw BAD. 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 BAD step by step
- Pick a venue from the table. For a coin this size the choice is usually short — 7 exchanges list BAD at all, and the table already shows what you will pay to leave as well as to buy.
- Fund the account. 7 of those exchanges take fiat, 6 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 BAD 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 BAD — FAQ
Where can I buy Bad Idea AI?
On 7 exchanges we track: MEXC, Bitget, CoinW, WEEX, BTSE and 2 more. The table above has each one with its trading fee, the payment methods it takes and what it charges to withdraw BAD.
What is the cheapest way to buy BAD?
MEXC, at $0.50 to buy $1,000 of BAD and withdraw it — $0.50 in trading fee plus $0.00 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%.
Can I buy BAD with a credit card?
Indirectly, yes. 6 of the exchanges listing BAD accept a card, but the card almost always buys a major asset — USDT, USDC, BTC — which you then swap for BAD 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 BAD?
Every exchange charges one, as a flat amount of BAD per network rather than a percentage. We do not have a priced figure for all of the venues listing BAD yet — the BAD withdrawal fee page has whatever each exchange publishes.
Is it safe to leave BAD 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 BAD 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.
