Kaspa

Not really. Higher network difficulty and dropping block rewards make GPU mining largely unprofitable. ASICs now dominate in efficiency.

Kaspa uses a blockDAG (GHOSTDAG) architecture with fast block times (~1 sec), enabling scalable, decentralized mining.

Both are possible. Solo mining works with low hashrate thanks to blockDAG, but pools (e.g., WoolyPooly, F2Pool) are more reliable for steady rewards.

Electricity costs, ASIC efficiency, KAS market price, and increasing difficulty all heavily impact profitability.
