Ethereum co-founder Vitalik Buterin proposed Fast Confirmation Rules (FCR), aiming to reduce deposit confirmation time to approximately 13 seconds and optimize user experience. FCR provides early confirmation signals through validator attestations without requiring a hard fork. Despite concerns about centralization and honesty, it is still viewed as an important measure to improve network efficiency and is part of the Lean Ethereum roadmap.

Bitcoin has weakened again after recent sharp fluctuations, with the price briefly dropping to around $73,100, then rebounding to approximately $76,400. However, multiple indicators show that momentum continues to weaken. Cryptocurrency trading firm QCP Capital pointed out that although the current price is temporarily above $74,500, the structure remains fragile. If it fails to hold above $74,000 consecutively, it could trigger a new round of deleveraging and forced liquidations, dragging down the entire crypto asset market. QCP believes that short-term institutional support around $76,000 is particularly critical. If the rebound cannot break through $80,000, the risk bias will still lean downward. Meanwhile, macro and geopolitical factors are stacking up, amplifying uncertainty. Michael Burry, famous for starring in "The Big Short," warned that liquidity is tightening, and risk assets are under significant pressure. If Bitcoin falls below $70,000, institutional funding chains could be impacted; if it further drops to $60,000, some highly leveraged companies may face severe tests.

Allspring Portfolio Manager Rushabh Amin mentioned in a research report that the Federal Reserve's current interest rate is close to neutral levels and will not exacerbate inflation.

On January 20, news, prediction market Polymarket's latest data shows that former Federal Reserve Governor Kevin Warsh is significantly ahead in bets for the next Federal Reserve Chair, with his chances of being nominated rising to 62%. As current Chair Jerome Powell's term will end in May 2026, the market generally expects that U.S. President Trump may lean toward choosing a candidate with a more hawkish monetary policy stance, making Kevin Warsh a focal point. Public records indicate that Kevin Warsh served as a Federal Reserve Governor from 2006 to 2011, known for supporting relatively high interest rates during the global financial turmoil. He has long emphasized the importance of controlling inflation, even if this may impose some short-term constraints on economic growth. Compared to dovish policymakers who focus more on stimulating the economy, Warsh is typically seen as a classic hawk.

Odaily Planet Daily reports that Arthur Hayes states privacy will define the next wave of cryptocurrency transactions, with Zcash becoming the privacy beta. His family office Maelstrom has established a large Zcash position at a low price in Q3 2025, and currently Zcash is the second-largest liquid asset holding in its portfolio after Bitcoin. Arthur Hayes believes that as US political motives lean toward aggressive credit expansion, the increased dollar liquidity will support Bitcoin and privacy assets. Additionally, Maelstrom is shifting its research and portfolio strategies toward the zero-knowledge proof ecosystem.

According to ChainCatcher news, according to Golden Ten, Tickmill Group analyst Joseph Dahrieh said in a report that the dollar fell as investors took a cautious stance ahead of the Federal Reserve's latest meeting minutes. He said the market is looking for clearer signals from the minutes about the Fed's policy trajectory in 2026, with weak liquidity at the end of the current year and price action likely to be amplified. If the minutes clearly lean towards further rate cuts in 2026, this could put pressure on the US Dollar and US Treasury yields.

Former Bank of Japan Deputy Governor Masazumi Wakatabe stated that Japan needs to raise the neutral interest rate through fiscal policy to support rate hikes, but should avoid tightening monetary policy too early. Analysts are cautious about this, believing that his remarks lean towards the government stance and may be aimed at opposing the central bank's upcoming rate hike.
