Bitcoin mining economics revolve around the hash price, a key determinant of miners' earnings, influenced by factors like block rewards, fees, and equipment efficiency. Miners prioritize the hash price over Bitcoin's market value, considering it akin to a commodity price that reflects the worth of their computational power. This metric experiences short-term fluctuations and long-term trends, impacted by market demand, computing efficiency, and energy costs. Consequently, miners must carefully forecast and account for the hash price in their business strategies. Meanwhile, custodians play a vital role in Bitcoin's scalability, offering services for those who prefer not to self-custody, necessitating trust and reliability. Despite efforts to reuse mining heat, its low quality and temperature pose limitations compared to other sources. Trust and reputation remain paramount in the Bitcoin industry, particularly for custodial and lending services, cultivated through consistent quality and accountability to customers.
