Crypto exchange reviews and referral codes, tested with real accounts
We open accounts, run deposits and withdrawals, and verify every code before it goes live.
Promokoin covers what matters when you pick an exchange: real fees, working referral codes, and bonuses that exist. Since we're not marketing guys, every review is hands-on, not a press kit. When the competition advertises a discount that isn't real, we say so and publish the actual number.

Fees and bonuses may change. We check prices live using our verified referral sign-ups, but always verify on the exchange before moving funds or opening any account.
How we evaluate exchanges
Every exchange goes through the same six checks, so the comparison stays fair and consistent.
Fee analysis
We record maker and taker fees for spot and futures at the default, non-VIP tier. That tells you the real cost of trades across BTC, USDT, USDC and common pairs, not just the best marketing.
Liquidity & volume
Trader counts, top-of-book depth, cross-exchange comparisons and slippage tests. We quote real depth on major pairs, not last traded numbers.
Security & track record
We review cold storage, past hacks and fund losses, proof-of-reserves disclosures, licenses and KYC policies, including what proof-of-reserves tools can't cover.
Product range
Listed markets, supported tokens and withdrawal chains, and the product set: trading, earn, loans, copy trading, tools, and retail categories like tokenized stocks and real-world assets.
User experience
We test account registration, KYC speed, mobile apps and a deposit/withdrawals flow from fiat to trade and back to fiat on average devices, not sponsored tests.
Monthly re-checks
Exchanges are re-checked every month. If fees, products, or uptime change, we correct the page and refresh the "Updated" date.

Why trust Promokoin
We are a small, independent team. Here is what sets us apart from other comparison sites.
No paid rankings
Exchanges cannot pay to appear higher on our tables. Ratings come from data, not deals.
Real authors
Every review is written by a real person who uses and tests these platforms, not by an agency.
Source-linked data
Every volume, fee and figure links to its source — CoinGecko, CoinMarketCap or the exchange's real fee page — so you can check it yourself.
No fake bonuses
50% OFF → 20% real.
When a site advertises a discount that doesn't exist, we say so. We publish the real bonus and the conditions, not the marketing number.
