lang=\"en\" dir=\"ltr\">JUST IN: \ud83d\udea8 Bitcoin is now at risk of a 51% attack as two mining pools control over 51% of the hash power. <a href=\"https:\/\/t.co\/QKkMziOy1C\">pic.twitter.com\/QKkMziOy1C<\/a><\/p>\n<p>\u2014 Leo Lanza | ETHisDigitalOil.eth (@l3olanza) <a href=\"https:\/\/twitter.com\/l3olanza\/status\/1957807617964679462?ref_src=twsrc%5Etfw\">August 19, 2025<\/a><\/p>\n<\/blockquote>\n<p><a href=\"https:\/\/x.com\/BawdyAnarchist_\/status\/1957834509514051621\">Foundry even mined eight consecutive blocks in a row<\/a>, an event that is extremely rare and has heightened fears of network centralization.<\/p>\n<p>With over 51% of the hash power concentrated in just two entities, experts warn that Bitcoin is technically vulnerable to a 51% attack.<\/p>\n<p>In such a scenario, the dominant miners could potentially reorganize blocks, censor transactions, or undermine trust in the network.<\/p>\n<p>While such an attack would be extremely costly and perhaps self-defeating, the centralization trend has raised red flags across the community.<\/p>\n<h2>Rising empty blocks and collapsing fees<\/h2>\n<p>Alongside the hash power imbalance, analysts have noted an increase in the number of empty blocks being mined.<\/p>\n<p>Empty blocks generate lower transaction fees, which has led to collapsing revenues for miners and less efficient network usage.<\/p>\n<p>This situation has further fueled concerns about the long-term sustainability of the Bitcoin ecosystem, particularly as users demand greater efficiency from the blockchain.<\/p>\n<p>Although some commentators argue that a 51% attack would require an astronomical investment, estimated at around $1.1 trillion, they also admit that the risk of manipulation grows when power becomes too concentrated.<\/p>\n<p>Supporters of Bitcoin believe that no rational actor would spend such sums to destroy the very network that sustains their investment.<\/p>\n<p>Still, the perception of risk is enough to shake market confidence.<\/p>\n<h2>Bitcoin price slides toward key support levels<\/h2>\n<p>The security fears are unfolding at a delicate moment for Bitcoin\u2019s price.<\/p>\n<p>After reaching an all-time high of $124,000 just last week, <a href=\"https:\/\/coinmarketcap.com\/currencies\/bitcoin\/\">Bitcoin (BTC)<\/a> has fallen sharply to around $113,000.<\/p>\n<p>The cryptocurrency is now approaching a crucial support level near $110,530, where buyers are expected to step in.<\/p>\n<p>If the price holds above that level, a rebound toward $120,000 and eventually $124,474 could follow.<\/p>\n<p>Some analysts like popular X commentator <a href=\"https:\/\/x.com\/BitQua\/status\/1957421475931070905\">BitQuant<\/a> are confident that Bitcoin is still on track to reach $145,000 without ever dipping below the six-figure mark.<\/p>\n<p>However, if Bitcoin breaks below the $110,530 support zone, the decline could deepen toward $107,000 or even $100,000.<\/p>\n<p>Short-term charts show bearish momentum, with the relative strength index in negative territory and the 20-day moving average sloping downward.<\/p>\n<h2>Macro fears add pressure on crypto markets<\/h2>\n<p>Beyond the technical charts, macroeconomic shocks are also weighing on sentiment.<\/p>\n<p>A recent shift in Federal Reserve policy, combined with Wall Street warnings about the newly passed Genius Act stablecoin bill, has unsettled investors.<\/p>\n<p>There are fears that the legislation could trigger a flood of withdrawals worth up to $6.6 trillion, posing systemic risks to both banking and crypto markets.<\/p>\n<p>\u00a0<\/p>\n<p>\u00a0<\/p>\n<div class=\"post-meta\">\n<hr class=\"mb-6\"\/>\n<h6 class=\"text-3xl  mb-4  text-green-300\">Share this article<\/h6>\n<hr class=\"mb-6\"\/>\n<h6
