How to Choose a Crypto Exchange: 5 Checks for Futures Traders
Rankings change and many are paid placements. These five checks can be verified on the exchange's own pages in a few minutes. Below, each check is applied to OKX, Bybit and MEXC with the date we looked, followed by what the October 2026 Binance hack means for choosing an exchange.
The five checks
Can you use it where you live?
Every exchange lists countries it does not serve and products it limits. Read the restricted-countries list before you deposit; if your country is on it, stop there.
What does a trade cost?
Compare the published maker and taker rates for the product you will trade, then the round-trip cost of your usual size. A tenth of a percent matters more at high leverage because the fee is charged on the full position value.
Does it show its reserves?
Proof of reserves lets you check that the exchange reports holding at least as much as users have deposited. Look for how often it is published, whether you can verify your own balance, and what it does not cover (liabilities outside user balances).
Who regulates it, for you?
An exchange can hold a licence in one country and none in yours. Check which entity serves your region and any warning a regulator has published about the exchange.
Do the product rules suit you?
Margin modes, liquidation rules, funding intervals and maximum leverage differ by exchange and region. Read the help pages for the contract you will trade.

After the 2026 Binance hack: what to check about security
On or about 29 October 2026, attackers took about $6.3 billion in token assets from Binance. In its own update the next day, Binance said its hot wallets were compromised, that it would absorb the loss through its Secure Asset Fund for Users (SAFU) and its corporate treasury, and that it had paused withdrawals while deposits kept working (Binance Security Incident Update #2, 30 Oct 2026). On 12 November the US Justice Department said the FBI attributes the theft to North Korean hackers it calls TraderTraitor and that it had court authorisation to seize or restrain more than $1.2 billion of the stolen assets (DOJ press release). It was not the first theft of this size: in February 2025 about $1.5 billion was taken from Bybit, which the FBI also attributed to North Korea (FBI PSA250226).
Large exchanges can be hacked, and no page can tell you in advance which one will be next. What you can check is how much an exchange shows about its reserves, how it would cover a loss, and how it has behaved when something went wrong.
- A recent proof of reserves. Look at the snapshot date, whether you can verify your own balance in it, and whether the ratio is reported per asset. A snapshot shows holdings against user balances on one day; it does not list every liability.
- A loss-cover fund you can look up. Binance named SAFU together with company funds. MEXC says its Guardian Fund holds 100 million USDT and 2,000 BTC and publishes the wallet addresses so the balance can be checked on-chain (MEXC release, 1 Oct 2026, self-reported). A fund smaller than a possible theft cannot cover it alone; Binance used its treasury as well.
- The futures insurance fund is a different thing. On OKX, Bybit and MEXC the insurance fund on a contract page absorbs losses from liquidations that close below bankruptcy price. It is not a promise to repay users after a theft.
- How past incidents were handled. Check whether the exchange published updates while it happened, said who bears the loss, and later released a post-incident report.
- Your own account settings. Turn on two-factor authentication and a withdrawal address whitelist where the exchange offers them, and keep on the exchange only what your open positions and planned trades need. Crypto held on an exchange is generally not covered by bank deposit insurance.
Sign-up offers are not a selection criterion
Discounts shown at sign-up are small next to the cost of using an exchange you cannot legally use or whose reserves you cannot check. If an exchange passes the five checks, our referral pages quote exactly what its sign-up page shows (OKX, Bybit, MEXC). CoinPopBit may earn a commission when you sign up through those links, at no extra cost to you.
