The Bitcoin (BTC) mining difficulty has reached an unprecedented high of 134.7 trillion, marking a significant development for the cryptocurrency network. This surge follows a previous peak in August, where expectations for decline proved inaccurate. Despite this rise, Bitcoin’s hashrate has declined to 967 billion hashes per second, down from its record-high level of over 1 trillion hashes per second observed on August 4th, according to CryptoQuant. This increased difficulty adds strain to large mining firms already operating within a highly competitive industry characterized by thin profit margins. Concerns about the centralization of Bitcoin mining have been heightened as the escalating need for computing power presents challenges for smaller players. Meanwhile, larger entities in the sector continue to dominate, potentially leading to fewer opportunities for solo miners. However, small and solo miners are finding success, occasionally securing block rewards worth over $344,000, including three miners who successfully added blocks to the Bitcoin ledger in July and August. Notably, these miners earned substantial rewards of nearly $350,000, $373,000, and $373,000 respectively, highlighting the potential for independent operators in the industry.
