Marathon Digital Holdings (MARA) CEO Fred Thiel recently stated that as competition intensifies and energy costs rise, the profit margins for Bitcoin mining are continuously shrinking. In the future, only mining companies with access to low-cost energy or those transitioning to the fields of artificial intelligence (AI) and high-performance computing (HPC) are likely to survive. Thiel pointed out that some mining companies have already shifted to AI and computing infrastructure, while hardware manufacturers and large institutions operating their own computing power are further squeezing the survival space for small and medium-sized miners. He warned that by 2028, when Bitcoin block rewards are halved to about 1.5 BTC, if transaction fees or the coin price do not rise significantly, most mining companies' business models will become unsustainable.
