   A mining operation uses a mix of GPU and ASIC miners. The operator wants to switch from mining coin A to coin B, which uses a different algorithm. What is the most important consideration?

   • AThe mining software must be updated to support coin B's network.
   • BThe electricity cost will change because coin B uses a different algorithm.
   • CThe ASIC miners may not be compatible with coin B's algorithm, while GPUs are more flexible.
   • DThe mining pool must be changed to one that supports coin B.

   A miner joins a mining pool with a PPS (Pay-Per-Share) reward system. The pool finds a block, but the miner's contribution to the pool's total hash rate is only 0.5%. What will the miner receive?

   • AA fixed payout based on the number of shares submitted, regardless of whether the pool finds a block
   • BA payout only if the pool finds multiple blocks in a row
   • CA share of the block reward proportional to their hash rate contribution, but only if the pool finds a block
   • DA payout that is reduced by a penalty if the miner's hash rate fluctuates

   How does Proof of Stake (PoS) differ from Proof of Work (PoW) in terms of block validation?

   • APoS requires validators to lock up a stake of coins, while PoW requires computational work
   • BPoS uses more electricity than PoW
   • CPoS requires specialized hardware like ASICs
   • DPoS allows anyone to mine without any investment
