Tether’s USAT launch builds on USDT’s dominance rather than starting from scratch

Tether announced the launch of USA₮ (USAT), a federally regulated, dollar-backed stablecoin, on January 27. Unlike new entrants, Tether leverages the established dominance and infrastructure of its flagship USDT, which has a market cap exceeding $186 billion and supports global trading, remittances, and cross-border settlements. USAT is designed to comply with U.S. federal regulations, enabling adoption by U.S. platforms and institutions that are restricted from using offshore stablecoins. Its success will depend not on branding but on integrating into existing liquidity networks and regulatory frameworks, allowing segmentation between offshore (USDT) and onshore (USAT) activity. Early exchange availability and usage in institutional settlement, trading, or payments will be key indicators of its traction.

Is Bitcoin’s top still ahead? Decoding impact of equity divergence

Bitcoin is experiencing bearish pressure and a short-term downtrend, with market sentiment suggesting a local top may be forming. However, its historical correlation with U.S. equity markets like the S&P 500 presents a potential upside opportunity. Since September 2025, Bitcoin has diverged from equities, declining roughly 30% while major indices gained. This underperformance may narrow if Bitcoin catches up through upward price movement. Key challenges include persistent capital outflows, with U.S. spot Bitcoin ETFs seeing $4.68 billion in net sales since November. Despite this, Bitcoin's price has held relatively stable, declining only about $2,900, supported by strong hashrate levels and miner accumulation. A significant risk is a $7 billion outflow from stablecoins, reflecting reduced risk appetite and posing a downside threat similar to the 2021 Terra-Luna collapse. Overall, Bitcoin could be poised for a rebound aligned with equities, but stablecoin outflows remain a critical near-term risk.

Crypto Entrepreneurs, VCs Have Become Immune to 'Storytelling'

Cryptocurrency funding surged to $50.6 billion in 2025, a 200% increase from 2024, but the growth was largely driven by mergers and acquisitions (M&A), which accounted for over 40% of total funding—up from just 9% the previous year. While venture capital (VC) investments still grew by 70%, their share of overall funding dropped significantly. VCs shifted focus toward later-stage rounds (Series B and C), which more than doubled, while early-stage funding (Pre-Seed, Seed, and Series A) declined. This indicates a market preference for lower-risk, proven ventures with existing traction, such as robust user bases and distribution networks, rather than speculative early ideas. Major acquisitions, like Coinbase’s purchase of Deribit and Naver’s acquisition of Dunamu, highlight this trend toward consolidation and leveraging established "flywheels." The data suggests that in 2026, capital concentration will continue, with investors prioritizing clear metrics, regulatory resilience, and sustainable business models over narrative-driven pitches. Early-stage founders must adapt by focusing on tangible growth indicators and distribution strategies to attract funding in a more cautious investment landscape.

Ethereum inside major Cost Basis cluster as market weighs next move

According to Glassnode's onchain data, Ethereum is trading within a major cost basis cluster between $2,900 and $3,100, a key breakeven zone for a large share of holders. This dense concentration indicates heightened market sensitivity, where small price moves can significantly influence holder behavior. A secondary accumulation zone exists between $3,300 and $3,500, while support thins below $2,700. Currently trading around $2,930–$2,950, ETH remains below its key moving averages and within a broad sideways range. The market shows muted momentum, with moderated volume, suggesting price discovery is occurring through absorption rather than trend expansion. Onchain positioning indicates participants are still negotiating value without a clear directional catalyst.

These Key Bitcoin On-Chain Metrics Suggest BTC Has Not Yet Reached Its Bottom

Based on key on-chain metrics, Bitcoin (BTC) has likely not yet hit its cycle bottom despite ongoing price declines. Analysis from Alphractal highlights that the Net Unrealized Profit/Loss (NUPL) metric, while declining, remains in positive territory, indicating that most holders are in profit rather than loss. Historically, a true bottom occurs only when NUPL turns negative, signaling full capitulation. Additionally, the Delta Growth Rate has turned negative, suggesting the end of speculative activity and the beginning of an accumulation phase. Following a recent pullback below $90,000, bearish sentiment has intensified. Swissblock notes that losing the $89,200 support level has increased market risk, though bulls are defending the $84,500 level. A break below this could lead to a deeper correction toward $74,000. However, if support holds, a liquidity sweep and potential long entry opportunity may occur. Current data indicates excess supply and uncertainty, meaning more time or data validation is needed to confirm a market bottom.
