Foundry USA and AntPool now control over half of Bitcoin\u2019s hash power.
\nBitcoin price is slipping toward $110,530, a crucial support level.
\nMacro fears and Fed shifts add pressure to already weak crypto markets.<\/p>\n
After Monero\u2019s 51% takeover, two Bitcoin mining pools have sparked fears of a potential 51% attack on Bitcoin.<\/p>\n
Notably, the developments have raised critical questions about the security of the Bitcoin network and the stability of the wider crypto market.<\/p>\n
Also, the concerns over mining centralisation have intensified just as BTC faces steep price declines and broader macroeconomic pressures.<\/p>\n
Two major mining pools, Foundry USA and AntPool, now control more than half of Bitcoin\u2019s total computing power.<\/p>\n
JUST IN: \ud83d\udea8 Bitcoin is now at risk of a 51% attack as two mining pools control over 51% of the hash power. pic.twitter.com\/QKkMziOy1C<\/a><\/p>\n \u2014 Leo Lanza | ETHisDigitalOil.eth (@l3olanza) August 19, 2025<\/a><\/p>\n\n 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 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 In such a scenario, the dominant miners could potentially reorganize blocks, censor transactions, or undermine trust in the network.<\/p>\n While such an attack would be extremely costly and perhaps self-defeating, the centralization trend has raised red flags across the community.<\/p>\n Alongside the hash power imbalance, analysts have noted an increase in the number of empty blocks being mined.<\/p>\n Empty blocks generate lower transaction fees, which has led to collapsing revenues for miners and less efficient network usage.<\/p>\n 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 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 Supporters of Bitcoin believe that no rational actor would spend such sums to destroy the very network that sustains their investment.<\/p>\n Still, the perception of risk is enough to shake market confidence.<\/p>\n The security fears are unfolding at a delicate moment for Bitcoin\u2019s price.<\/p>\n After reaching an all-time high of $124,000 just last week, Bitcoin (BTC)<\/a> has fallen sharply to around $113,000.<\/p>\n The cryptocurrency is now approaching a crucial support level near $110,530, where buyers are expected to step in.<\/p>\n If the price holds above that level, a rebound toward $120,000 and eventually $124,474 could follow.<\/p>\n Some analysts like popular X commentator BitQuant<\/a> are confident that Bitcoin is still on track to reach $145,000 without ever dipping below the six-figure mark.<\/p>\n However, if Bitcoin breaks below the $110,530 support zone, the decline could deepen toward $107,000 or even $100,000.<\/p>\n Short-term charts show bearish momentum, with the relative strength index in negative territory and the 20-day moving average sloping downward.<\/p>\n Beyond the technical charts, macroeconomic shocks are also weighing on sentiment.<\/p>\n 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 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 \u00a0<\/p>\n \u00a0<\/p>\n The post Bitcoin at risk of a 51% attack from two miners<\/a> appeared first on CoinJournal<\/a>.<\/p>","protected":false},"excerpt":{"rendered":" Foundry USA and AntPool now control over half of Bitcoin\u2019s hash power.
