👉Luxor, Blockspace's preferred mining pool

Bitcoin mining revenue changes every day. Difficulty adjusts. Fees move. Prices shift. And that makes it hard to plan. Luxor Pool’s Fixed Payouts let miners lock in revenue at a guaranteed daily rate for up to 18 months. According to Hashrate Index, miners who used rolling fixed payout strategies since the last halving have outperformed FPPS mining by up to 15 percent. Fixed Payouts give you predictable daily revenue, so you can plan, budget, and grow with confidence. With Luxor, uncertainty is optional. Learn more at luxor.tech/mining
