BTCC advertises up to 30,000 USDT for new users. The part a normal new user collects is about 45 USDT, from a task list on the newcomer page: 10 USDT for registering, 20 USDT for KYC, 10 USDT for a first deposit of 200 USDT (20 USDT for 500 USDT or more) and a 5 USDT coupon for a first futures trade, within 7 days of sign-up. A first copy trade adds 5 USDT, and 2,000 USDT of cumulative deposits within 30 days adds 30 USDT. The rest of the headline is fee credit tied to futures volume in the millions of USDT.
These rewards are trading fund vouchers and fee coupons, not cash. Trading funds act as margin and can absorb losses and funding fees but cannot be withdrawn, while profits made with them can. Moving funds out of the futures account cancels unused rewards, BTCC pages say to keep at least 5% of the deposit in futures, and unused rewards expire.
The referral program pays you 25% of the trading fees a friend pays from their own balance in their first 60 days, up to 500 USDT per friend, in USDT credited to your spot account the next day, so it can be withdrawn. Fees paid with bonus coupons do not count, which keeps the realistic payout per friend at a few USDT. Other BTCC pages advertise 35%, 45%, 50% or 60% commissions, but those carry no published terms.
