During the week of September 29 to October 5, 2025, the cryptocurrency market demonstrated a pronounced upward trend, primarily driven by Bitcoin's strong performance and the consolidation of major altcoins. Bitcoin repeatedly historical highs, surpassing the $125,000 mark by October 5, representing the week's key event. The rally was supported by both institutional investments and positive macroeconomic expectations.
Bitcoin Market and Key Levels
Bitcoin started the week around $112,000, then experienced sustained growth, breaking through important psychological barriers at $114,000 and $119,000 in early October. On October 3-4, the premier cryptocurrency exceeded $120,000, and on October 5 set a new all-time high ($125,708). The rally was accompanied by significant short position liquidations, reinforcing market bullish sentiment. Analysts attribute the growth to seasonality (October has historically been strong for BTC), ETF capital inflows, and expectations of U.S. monetary policy easing. Experts provide optimistic forecasts, up to $200,000 by year-end under favorable conditions.
Major Altcoin Performance
Ethereum also strengthened - in early October ETH maintained a $4,100-4,600 range, rising to $4,500 and above, with further growth expected after the Pectra network upgrade in Q1 2026. Among top cryptocurrencies, Solana stands out for active development and institutional demand, alongside BNB with notable fee reductions to $0.005 on BNB Chain. Lesser-known coins like Zcash and Pump.fun also showed rapid growth, demonstrating high volatility.
Institutional and Technological Developments
Key institutional news includes active crypto reserve accumulation by companies like Bit Digital and Strategy, plus Binance's launch of crypto-as-a-service for traditional financial institutions. Tether acquired additional Bitcoin worth approximately $1 billion, aggressively expanding its reserves. Additionally, Visa is testing USDC and EURC stablecoins for cross-border payments, highlighting digital assets' gradual integration into global financial systems. U.S. regulatory developments include accelerated simplification of crypto ETF listings, potentially stimulating altcoin capital inflows and enhancing market liquidity. CIS countries are tightening regulations while maintaining crypto interest.
Geopolitical and Regional Context
Regionally, Kazakhstan's achievements are noteworthy with a state crypto fund using BNB as the base asset, plus the shutdown of the largest illegal crypto exchange. Russia is discussing penalties for cryptocurrency transactions, indicating enhanced oversight. Meanwhile, market leaders like Pavel Durov express confidence in Bitcoin reaching $1 million, demonstrating long-term optimism among leading experts.
Summary

Bitcoin overcame crucial price thresholds, reinforcing its position as the industry's primary asset, while altcoins show promising momentum amid institutional interest and technological upgrades. For newcomers, it's essential to understand that such movements result from coordinated macroeconomic, investment, and infrastructure developments.
