Hook
A perpetual contract that pays you 110% of your fee back as a token reward sounds, at first glance, like a gift from a failing platform desperate for volume. It is. The structure is mathematically inverted: the rebate exceeds the cost, meaning every transaction is a net negative for the issuer in token terms. HTX's Phase 3 TradFi Trading Mining campaign, running from September 14 to 20, offers Maker rewards at 110% and Taker rewards at 105% of paid fees. The entire fee pool is supposedly recycled into $HTX buybacks and burns. Let me walk through the accounting — because somewhere in this loop, the math either reconciles or it doesn't.

Context
HTX, the rebranded successor to Huobi, launched its third iteration of a TradFi-style derivatives mining program. The product lineup spans 20 contract pairs across four asset categories: precious metals (XAU, XAUT, PAGG), US equities (NVDA, TSLA, GOOGL), equity indices (SPX500, QQQ), and commodities (USOIL). The structure is classic centralized exchange synthetic exposure — perpetual contracts priced against traditional assets, settled in USDT, with no real underlying custody. Think CFD, not RWA. The platform markets "negative fee" trading, a phrase that deserves immediate scrutiny since it conflates a token rebate with a structural fee advantage.
The campaign mechanics: users trade these synthetic contracts, pay standard maker/taker fees, and receive $HTX tokens equivalent to 110% (maker) or 105% (taker) of those fees. Simultaneously, 100% of collected fees flow into a $HTX buyback-and-burn pool. A six-day window. Phases one and two already executed.

Core
The first thing I check when I see a "fee rebate > 100%" design is the token source. If rewards are denominated in $HTX and the buyback is funded by the same fees being rebated, we have a closed loop that looks like this:
