Bitcoin miners are experiencing heightened financial strain, with indicators reaching levels akin to past bear market pressures, according to CryptoQuant analyst Darkfost. The Miner Financial Health Ratio, a key metric assessing miner profitability, is fluctuating between 10% and 30% on a 7-day average. This range suggests significant operational challenges, as such low levels are typically observed during peak bear market phases. The analysis considers factors like miner issuance revenue, block time, transaction fees, and overall revenue, highlighting the current financial stress on mining enterprises.
