Bitcoin's Great Consensus Cleanup soft fork targets legacy vulnerabilities

Grade Abullish AI signal$BTC

Bitcoin's proposed BIP-54 Great Consensus Cleanup soft fork aims to fix four longstanding vulnerabilities in the network's consensus rules, strengthening security without changing Bitcoin's economic model or adding new features. The proposal addresses difficulty-adjustment time-warp attacks, slow-validation poison blocks, Merkle tree weaknesses and duplicate coinbase transaction risks, while MARA Pool and ViaBTC have begun producing compatible coinbase transactions on mainnet. Growing miner readiness and successful testing could improve the proposal's chances of becoming Bitcoin's next soft fork and strengthen long-term network security.

Robert Kiyosaki Can’t Wait for the Next Gold, Silver, and Bitcoin Crash

Robert Kiyosaki says he is waiting for the next crash in gold, silver, and Bitcoin so he can buy more at lower prices, citing soaring global debt and declining confidence in fiat currencies. US federal debt has reached approximately $40.6 trillion, while gold recently rebounded 2.34% above $4,023, silver jumped nearly 4% toward $52, and Bitcoin recovered to around $80,500. Kiyosaki's buy-the-crash strategy could attract renewed interest in hard assets and Bitcoin during future selloffs, although further declines and difficulty timing market bottoms remain risks.

Crypto's Washington hopes fade, but Grayscale and BlackRock see growth ahead

Grayscale and BlackRock say crypto's long-term growth prospects remain intact despite weakening U.S. legislative support following Democrats' midterm election victories. Grayscale estimates that 80% to 85% of global cryptocurrency activity occurs outside the U.S., while BlackRock sees limited impact from political changes on its crypto business. Continued global demand and institutional adoption could support crypto's expansion, although stalled U.S. legislation may slow regulatory progress and broader market conditions could pressure digital assets.

Crypto PACs eye 2028 “new map” as Democrats take Congress

Crypto PACs face a tougher political environment after Democrats won control of both chambers of Congress, with the industry's roughly $64 million effort to keep Republican Jon Husted in Ohio failing as Sherrod Brown reclaimed the Senate seat. Crypto super PACs spent approximately $176 million across 100 races, while Fairshake and affiliated groups retain more than $67 million heading into the 2028 elections; Elizabeth Warren is positioned to chair the Senate Banking Committee. Increased congressional scrutiny could slow crypto legislation and intensify regulatory pressure, although pro-crypto lawmakers and existing legislative progress may limit the impact.

Oil tanks, stocks leap on US midterms

Global markets rallied as Democrats' midterm election victory eased political uncertainty, while Brent and WTI crude plunged amid hopes of progress toward ending the US-Iran conflict. The Dow gained 3%, the S&P 500 rose 1.6%, and the Nasdaq advanced 1.4%, while Brent fell nearly 20% and WTI dropped 15% so far this week. Lower oil prices could ease inflationary pressure and support stocks and bonds, while expectations of a potential end to the Iran conflict may keep pressure on crude.
