Bitcoin and Ethereum Surge on Institutional Interest and Technical Catalysts
Bitcoin and other major cryptocurrencies have entered October on a strong note, boosted by renewed institutional interest and upcoming technical catalysts. Despite rising bond yields and profit-taking from investors following the summer rally, Bitcoin's price has held up well, with $2.4 billion in inflows into U.S. spot exchange-traded funds (ETFs) during the week ending September 25.
This marks the strongest weekly figure since October 2025, with total inflows reaching approximately $4.9 billion since August 19. Analysts at JPMorgan identified $85,000 as the estimated average production cost for Bitcoin, noting that the token recently moved above this key threshold after spending about 280 days below it.
Ethereum also posted a nearly 7% gain in September, with institutional investors showing renewed interest, including over $1.5 billion in ETH purchases by BlackRock's ETF products over a 20-day period. The upcoming Glamsterdam upgrade is seen as a potential catalyst for the network.
