As ASIC manufacturers flood the market with specialized hardware for most major coins, Kaspa (KAS) has emerged as the last major cryptocurrency that remains genuinely profitable for GPU miners, thanks to its unique GhostDAG protocol architecture.
Daily Earnings
At current KAS prices and network hashrate, an RTX 4090 earns approximately $5.50/day before electricity costs. Running at 450W draw, at a typical $0.10/kWh electricity rate, this translates to $4.42/day net profit—a strong return compared to alternatives.
