Choosing a crypto exchange is the single decision that affects every trade you'll make for the next year. Pick the wrong one and you'll bleed cost on fees, fight bad liquidity, lose access to assets you want, or — worst case — lose funds to an insolvent venue. This is a practical, opinionated checklist for picking a CEX or DEX that actually fits your strategy, built around the live data in the DEX Ranking and CEX Ranking on dexcex.io.
Step 1 — Define what you actually need
Most bad exchange choices come from skipping this step. Before you compare a single venue, write down what you actually want to do.
- Spot only, perps only, or both?
- Fiat on-ramp and off-ramp required, or are you bringing crypto in from elsewhere?
- Mostly blue chips (BTC, ETH, SOL, top stablecoins) or long-tail altcoins?
- Active trading (multiple trades per day) or buy-and-hold?
- Do you require self-custody, or are you comfortable with a custodial venue?
- Which jurisdictions can you legally use?
Your answers immediately split the universe — for self-custody you're shopping the DEX Ranking, for fiat-heavy spot trading you're shopping the CEX Ranking, and for non-custodial perps you're in the Derivatives DEX Ranking on dexcex.io.
Step 2 — Filter by trust and operational track record
Before fees or features, screen for venues you can actually trust with your assets (custodial) or your transaction flow (non-custodial).
For CEXs
- Exchange score above 6 in the CEX Ranking — the metric is designed to penalise wash trading and reward genuine markets.
- Multi-year operating history through at least one bear market.
- Public proof-of-reserves (with matched proof-of-liabilities, ideally).
- Clear corporate jurisdiction and licensing footprint.
For DEXs
- Top liquidity score in the relevant DEX Ranking view (spot or derivatives).
- Audited contracts from at least one reputable security firm, and a meaningful bug bounty.
- Long, clean post-launch history — the longer the contract has held value, the more economic security it has.
- Healthy weekly volume change — venues drifting toward zero are often quietly being abandoned.
Step 3 — Match liquidity to your trade size
An exchange with $5B daily volume but $20k order-book depth is not the same product as one with $1B volume and $500k depth. Liquidity at your trade size is what matters, not the headline number.
- Estimate your typical trade size in USD.
- On a CEX, open the order book of your main pair and check depth at ±0.1% from mid.
- On a DEX, simulate the swap in the venue or a routing aggregator and read the price impact.
- Discard any venue whose best price slippage at your trade size exceeds the trading fee.
Step 4 — Compare effective fees, not headline fees
Headline maker/taker fees are the start of the comparison, not the end. Compute an effective per-trade cost that includes everything you'll actually pay.
- CEX effective fee = base maker/taker × (1 - VIP discount) × (1 - native-token discount) × (1 - referral rebate) + average spread.
- DEX effective fee = swap fee + average gas cost / trade size + average price impact + MEV cost (where applicable).
- For perp venues, add a funding-rate budget for the average position holding period.
- Always check withdrawal fees against the network you'll use most (Tron, Solana, Arbitrum, Base, etc.).
Step 5 — Check product and asset coverage
An exchange that's perfect on cost is useless if it doesn't list the asset or product you trade. Run a coverage pass before committing.
- Search the venue for every asset on your watchlist — not just BTC and ETH.
- Confirm the products you need (spot, perps, options, margin) are available in your jurisdiction.
- Verify the deposit and withdrawal networks for your stablecoin of choice — USDT-Tron, USDC-Solana and USDC-Base have very different costs.
- If you need fiat off-ramps, confirm the rails work for your bank in your country.
Step 6 — Stress-test with a small account
Every exchange looks fine until you actually use it. Before consolidating capital, run a small account through the venue for a week or two and rate it on the things that matter.
- Deposit a small amount via your real on-ramp.
- Place a few real orders at typical sizes and check fills, slippage and fee receipts.
- Withdraw to your own wallet to confirm the off-ramp and timing.
- Test mobile and desktop UI for the workflows you actually use.
- Open a support ticket on a non-urgent question and judge the response.
Step 7 — Build a two-venue setup, not a single point of failure
Top traders almost always run at least two venues for the same product type. A single exchange is a single point of failure — maintenance windows, regional restrictions, sudden delistings or KYC re-verifications can lock you out exactly when you need to act.
- Primary CEX — your default for most spot and perp activity.
- Backup CEX — different jurisdiction, ready to absorb flow if the primary goes down.
- Primary spot DEX — for long-tail tokens and self-custodied positions.
- Optional perp DEX — non-custodial leverage when you don't want collateral on a CEX.
