Mid-tier Bitcoin miners are exceeding expectations following the recent halving event, which reduced mining rewards from 6.25 to 3.125 BTC. Despite tighter profit margins, these miners have adapted swiftly, leveraging lower network difficulty and modern ASIC hardware to maintain competitiveness. This development indicates a potential trend towards decentralization in Bitcoin mining, as smaller operations gain a foothold. Investors are increasingly focusing on these mid-sized miners, recognizing their growing influence in the post-halving landscape.
