Ethereum Price Crash: Fusaka Upgrade on the Horizon – What does it mean?
On October 9, 2025, developments around Ethereum show a dynamic situation in the crypto market. The current price of Ethereum (ETH) is $4,460 after the cryptocurrency fell 3% on Friday. This drop comes amid preparations for the planned Fusaka upgrade.
Ethereum core developers have set December 3rd as the tentative date for rolling out the Fusaka update to the mainnet. Fusaka aims to improve data optimization, increase gas limit, and expand blobspace on Ethereum. The rollout of this upgrade will take place in phases on the Holesky, Sepolia and Hoodi testnets, starting on October 1, 14 and 28, 2025.
Fusaka Upgrade Details
Fusaka consists of 12 Ethereum Improvement Proposals (EIPs) that address data verification, storage optimization, increasing the block gas limit, and improving smart contract execution. After the successful launch of the Fusaka upgrade, the developers plan to expand the Blob capacity. Initially, the target and maximum blobs per block will be increased from 6/9 to 10/15 in the first month, followed by a further increase to 14/21 a week later.
The Fusaka upgrade follows the Pectra upgrade that launched in May, which improved user experience and staking efficiency. However, there are uncertainties regarding the tests as the developers struggle with bugs and how to fix them. At the moment the probability of a smooth process on the test networks is only 50/50.
Market analysis and liquidations
Last week, Ethereum also saw a significant futures liquidation worth $89.8 million. Of this, $83.5 million were long positions and $6.3 million were short positions. The price of ETH is currently in a test against the 20-day Simple Moving Average (SMA) after failing at a rejection point at $4,620.
If ETH can hold the 20-day SMA, it could find support around the 50-day SMA at around $4,300. There is even the potential for a rise to $5,300 if the price closes above trend resistance. However, a daily close below $4,200 could invalidate this bullish scenario and result in a decline to support around $4,000.
Meanwhile, Ethereum co-founder Vitalik Buterin has defended the design of the network's validator queue. This design is currently in focus as waiting times for unstaking assets are already 43 days. The outlook remains tense given the complex market conditions and upcoming technological updates.
