Bitcoin Starts Uptober at $83K as Crypto Hacks Hit $768M

Bitcoin entered October near $83,000 after gaining 6.33% in September, but the start of “Uptober” comes with significant macro headwinds. Rising Treasury yields, another potential Federal Reserve rate hike, and resistance around $85,000 could test the recovery.

Crypto security was also back in focus after hackers stole roughly $768 million in September, making it the worst month for exploits in 2026 so far. Bitget and the Liquid Network accounted for most of the losses.

Meanwhile, MetaMask began exiting some Ethereum staking validators from Lido as a precaution while it investigates a security incident affecting part of its infrastructure.

1. Bitcoin starts Uptober near $83,000

Bitcoin entered October at roughly $83,823 after posting a 6.33% gain in September. Historical data offers some support for the “Uptober” narrative, while spot Bitcoin ETFs recorded about $3.08 billion in net inflows over nine consecutive trading days through September 29.

Macro conditions remain a key risk. The 10-year Treasury yield reached 5.304%, while markets put the probability of another Fed rate increase in October at around 70%. Bitcoin is also confronting a large sell wall around $85,000–$85,500, with trading volume remaining subdued.

2. Crypto hacks reach $768 million in September

Crypto exploits caused approximately $768 million in losses during September, according to security firms CertiK and PeckShield, making it the worst month of 2026 so far. Bitget suffered the largest incident at roughly $387 million, while a vulnerability in the Liquid Network resulted in losses estimated at around $320 million.

Those two incidents accounted for roughly 92% of the losses tracked by PeckShield. However, more than $270 million from the Liquid exploit was reportedly returned, while Bitget has restored withdrawals and said its Protection Fund has been replenished above $300 million.

3. MetaMask exits Ethereum validators amid security investigation

MetaMask began exiting some Ethereum staking validators from Lido after identifying a potential security threat affecting part of its infrastructure. The company said it is investigating the incident with external security partners and has identified no immediate threat to MetaMask wallets.

Lido expects the affected validators to complete their exits by October 7. The full exit, withdrawal, and re-entry cycle could take up to 45 days because of Ethereum’s extended validator entry queue, potentially resulting in temporary changes to staking rewards. No action is currently required from stETH holders.
