Key Takeaways
- Bitcoin mining is dominated by large-scale operations using advanced hardware, making it challenging for smaller miners to compete.
- Investing in mining stocks (e.g., Riot Platforms, Marathon Digital) offers indirect exposure to Bitcoin's growth without managing hardware.
- Companies prioritize sustainability and cost-efficiency, with expansions like Bitfarms' hydro-powered facilities and Core Scientific's AI pivot.
- Post-2024 halving reduced block rewards to 3.25 BTC, pressuring miner profitability and accelerating industry consolidation.
