BX BitMEX VS DY dYdX
These two exchanges don't share an obvious product overlap. Differences below come from our individual reviews of BitMEX and dYdX.
| BitMEX | dYdX | |
|---|---|---|
| Founded | 2014 | 2017 (dYdX Chain v4 launched October 2023) |
| Regions | Historically available worldwide outside the US and a short list of other restricted jurisdictions. As of September 2026 the exchange is winding down entirely and is not accepting new registrations anywhere. | Blocked for US, Canadian, UK, and sanctioned-territory persons at the protocol's terms-of-use level on the main front end; open-source front ends and direct chain access mean geographic enforcement is a terms-of-use matter rather than a technical one: read the restrictions before connecting a wallet. |
| Products | Spot, Perpetual futures, Dated futures | Perpetual futures (primary product), Spot (newer, limited rollout) |
| Maker fee | Moot given the September 2026 shutdown; historically a tiered volume-based schedule with maker rebates on major perpetual contracts. | Not yet verified |
| Taker fee | Moot given the September 2026 shutdown; historically around 0.075% at the base tier on flagship perpetual contracts, lower with volume. | Not yet verified |
BitMEX pros
- Invented the modern perpetual futures contract, the product type most derivatives exchanges reviewed on this site now offer
- Zero customer funds lost to hacks across more than 11 years of operation
- Deep historical liquidity on BTC and ETH perpetuals while the platform was active
- 24/7 multilingual support with a genuine (if inconsistent) track record of resolving disputes
dYdX pros
- Fully non-custodial: funds sit in your own wallet and on-chain margin account, never in a company-controlled hot or cold wallet
- Fully open source, including the validator software, indexer, and web/iOS/Android front ends, so no single company operates the exchange once it's running
- Deep specialization in perpetual futures with an order book and matching engine built specifically for that product, rather than derivatives bolted onto a spot exchange
- Governance and fee schedule are transparent and on-chain, set by DYDX token-holder votes rather than a private company's internal decisions
