The newcomer offer, advertised at up to $100, is a set of task-gated cashback vouchers from the Reward Center: roughly 10 USDT for a first deposit of about 50 USDT, 30 USDT for a first spot trade around 200 USDT of volume, and 60 USDT for a first futures trade. The futures threshold has varied between promotional runs, with official pages citing anywhere from 7,000 to 20,000 USDT of volume, so the realistic value for a casual new user is the first two tasks, around $40. The vouchers are fee rebates, not cash: they pay out only as you accumulate trading fees during their validity window, and unused value is recalled at expiry.
The referral program is the more genuine offer. Referrers earn a commission on their invitees' trading fees for 12 months, credited as real, withdrawable funds. The rate scales with CET holdings, from roughly 20% at the bottom of the ladder to 40% at 50,000 CET or more, and CoinEx's invite-based Ambassador program pays up to 50% in USDT with no 12-month limit. There is no turnover requirement; the money simply tracks the fees your referrals pay.
