How are bitcoins rewarded?
Could you elaborate on the mechanism behind rewarding bitcoins? Specifically, I'm curious about how the network ensures fair distribution of bitcoins as incentives for mining. Is it through a pre-set reward schedule, or does it vary based on certain conditions? Also, what are the main factors that determine the amount of bitcoins rewarded for each block mined? I'd appreciate a concise yet comprehensive explanation of the reward system in Bitcoin mining.
