Bitget Hack, Bitcoin Pullback, and Solana Upgrade Reshape Crypto Week

Crypto exchange Bitget confirmed it lost $387.5M to hackers in what has become the largest crypto theft of 2026. Attackers compromised a backend wallet system and spoofed transaction data, tricking Bitget's own authorization process into approving unauthorized payouts without ever touching private keys or cold storage. CEO Gracy Chen said IP addresses and on-chain patterns match techniques used by North Korean state-linked hackers, though the attribution has not been officially confirmed and law enforcement is now investigating.

Blockchain analytics firm Elliptic said the breach alone pushed North Korea's cumulative 2026 crypto theft total past $1B, echoing address patterns tied to last year's $1.5B Bybit hack. Bitget's $464M User Protection Fund will absorb the full loss, meaning customer balances remain intact, and the exchange began phasing in withdrawal restoration on September 28. Security firms Mandiant and SlowMist are conducting the third-party investigation.

Bitcoin Catches Its Breath as Macro Data Looms

Bitcoin stepped back from recent highs on Monday morning, trading down roughly 1% from Friday and falling more than 2% over the prior 24 hours as it retreated from the $84,000 level. Investors are shifting focus to a packed macroeconomic calendar following last week's hawkish Federal Reserve rate hike, which lifted the benchmark target rate to 4%. Key readings on core PCE, GDP, and nonfarm payrolls are all due before the week closes.

Despite the price dip, underlying demand signals stayed firm. U.S. spot Bitcoin ETFs recorded approximately $134M in net inflows on September 25, marking their seventh straight day of positive flows, while spot Ethereum ETFs pulled in roughly $86.95M to extend their own six-day inflow streak. Analysts say whether ETF momentum holds through the coming macro prints will be a central question for market direction.

Separately, Solana opened the activation window today for its major Alpenglow consensus upgrade, replacing the TowerBFT protocol with the new Votor system designed to cut voting transaction overhead across the network. The upgrade is among the most significant architectural changes to Solana's consensus layer since the chain launched and has been closely watched by validators and developers alike.
