Bitcoin Hashrate Drops 30% in Three Days Amid Winter Storms

The evidence overwhelmingly supports the statement. Multiple sources directly corroborate that a significant decrease in the Bitcoin hashrate occurred due to a US winter storm forcing mining operations to curtail power usage. Several sources provide specific figures that are highly consistent with the claim.Direct support for the "30%" figure comes from two industry sources, Bitget and Phemex, which explicitly report a drop of "approximately 30%" and a "30% drop," respectively. While these sources have moderate authority, their claims are reinforced by other, more authoritative reports. A news article from MEXC reports a "39% plunge" related to the same event. This slightly different figure does not contradict the claim but rather strengthens it by confirming a drop of a similar magnitude; variations in hashrate measurement methodologies and timing can easily account for the difference between 30% and 39%.Furthermore, highly authoritative sources like The Block, VanEck, and Bitcoin Magazine all confirm the underlying cause and effect: a winter storm led to a substantial, short-term decrease in hashrate. This establishes the high plausibility of the event described in the statement. There is no conflicting evidence presented. The lower-relevance sources either provide broad context (Congressional Research Service) or are not specific enough to challenge the claim (CoinDesk tag page, CoinMarketCap Facebook post). The convergence of evidence from multiple independent sources, all pointing to a major hashrate drop in the 30-40% range due to a specific, widely reported event, makes the statement very likely to be true.
