   A mining farm is planning to mine a new PoW coin that uses a memory-hard hashing algorithm. They currently have a large stock of CPUs and GPUs. What is the most appropriate hardware strategy?

   • AUse ASICs because they are always the most efficient.
   • BUse a mix of CPUs and GPUs, but CPUs will be more profitable.
   • CUse GPUs because memory-hard algorithms are designed to resist ASIC development.
   • DUse CPUs because they have the highest memory bandwidth.

   A small mining operation with a few GPUs wants to earn a steady income from a high-difficulty PoW coin. They are considering joining a mining pool. What is the primary benefit of joining a pool in this scenario?

   • AIt allows the miner to avoid running a full node.
   • BIt increases the probability of earning block rewards by combining hash power with other miners.
   • CIt guarantees a higher total reward than solo mining over any period.
   • DIt eliminates the need to pay transaction fees on mined blocks.
