   A hobbyist miner wants to start mining a cryptocurrency that is ASIC-resistant and can be mined with consumer hardware. They have a gaming PC with a high-end GPU and a modern CPU. They want to maximize their hash rate and efficiency. What should they primarily use?

   • AThe GPU, because it offers a higher hash rate and better efficiency than the CPU for most PoW algorithms
   • BAn ASIC miner, because it is the most efficient hardware available
   • CBoth CPU and GPU simultaneously to double the hash rate
   • DThe CPU, because it is less power-hungry and easier to configure

   A miner is part of a large mining pool that successfully mines a block. The block contains many transactions. How are the rewards from this block distributed among the pool participants?

   • AThe pool keeps the transaction fees and distributes only the block reward to miners.
   • BThe pool distributes the block reward and transaction fees proportionally to each miner's contributed hashrate.
   • CThe pool distributes rewards equally to all miners regardless of hashrate.
   • DThe miner who found the block receives the entire block reward, and transaction fees are shared equally.

   A mining farm has a fixed power budget of 500 kW and is choosing between two hardware options: 100 ASIC miners that each consume 5 kW and produce 100 TH/s, or 200 GPU rigs that each consume 2.5 kW and produce 20 MH/s. The farm's electricity cost is $0.05/kWh. The network difficulty is high and rising. Which option is more likely to be profitable in the long term?

   • AThe GPU rigs, because they are more versatile and can switch to other coins if profitability drops.
   • BThe ASIC miners, because they provide far more hashrate per watt, which is critical when difficulty is high.
   • CBoth options are equally profitable because they consume the same total power.
   • DNeither option is profitable because electricity costs are too high.
