Bitcoin Miners Face Risks Despite BTC Price Surge from ETF Launch

Bitcoin ETF launch has sent BTC price soaring, but mining firms' shares are flat or down except for CleanSpark (CLSK)
Mining firms' revenue typically rises with Bitcoin price, but upcoming halving will cut per-block rewards and could push out small miners
Some miners are expanding into AI cloud services, which can be more profitable per unit of energy than just BTC mining
CleanSpark stands out, massively outperforming Bitcoin over past year as it benefits from BTC transaction fees and cloud services
Miners that prepare for halving likely to retain investor confidence, though ETFs and miners present different risk/reward profiles
