Ethereum switched on its biggest capacity upgrade of 2025 this week, activating the Fusaka hard fork and triggering a quick positive response from the market.
The update merges the Fulu consensus layer with the Osaka execution layer. In simple terms, it changes how Ethereum moves and stores data. The goal is to process more transactions without giving up decentralization.
Fusaka brings two major upgrades.
The first is PeerDAS, a change to how data is handled across the network. Developers say it can increase Ethereum’s data throughput by up to eight times.
Fusaka is live on Ethereum mainnet!
– PeerDAS now unlocks 8x data throughput for rollups
– UX improvements via the R1 curve & pre-confirmatons
– Prep for scaling the L1 with gas limit increase & moreCommunity members will continue to monitor for issues over the next 24 hrs.

That extra room helps rollups the scaling networks built on Ethereum handle more activity at lower cost. When rollups get more space, apps can run smoother, fees can drop, and more users can move on-chain.
The second upgrade focuses on how people use Ethereum day to day.
New tools like the R1 curve and pre-confirmations are meant to make transactions feel faster and more predictable. Wallet actions should take less time.
Confirmations should be clearer. And basic tasks should feel less complicated, especially for people using Ethereum on their phones.
Together, the changes aim to make Ethereum simpler, cheaper, and easier to use, without changing what makes the network hard to control or shut down.

What Does BitMine’s $150M ETH Purchase Really Mean?
Fusaka could shape Ethereum’s price in a similar way to earlier upgrades. There is a clear example from last year.
Ethereum treasury firm BitMine added another large chunk of Ether to its balance sheet on Wednesday, purchasing $150M worth of ETH as part of its long-term accumulation strategy.

Tom Lee’s BitMine has just bought $150 million worth of Ethereum. The latest acquisition further strengthens BitMine’s position as one of the largest corporate holders of Ethereum, marking another step toward its publicly stated goal of controlling 5% of ETH’s total circulating supply.
The company has been steadily increasing its exposure to Ether through a series of high-value purchases, framing the buying campaign as a treasury-level bet on the network’s long-term role in finance, payments, and digital infrastructure.
The firm did not disclose the average price paid for the tokens or whether the purchase was executed through a single desk or split across multiple transactions.

Where Is Ethereum’s Strongest Support If Price Drops Again?
A new chart from a crypto analyst now shows Ethereum attempting to regain its footing after the latest sell-off erased nearly a month of gains.
On the 12-hour chart, ETH USD price has bounced from the late-November low near $2,630. It is now testing the $3,050 to $3,150 area.
This level is used to block rallies. That makes it a key test. Buyers now want it to act as support instead.
The short-term average is trending higher, indicating early signs of stability. But the Relative Strength Index is still below its midpoint. That shows selling pressure has eased, but bulls are not in full control yet.
If this zone holds, the next target sits near $3,650 to $3,700. That area has heavy selling interest. Analysts say a move there could follow as short sellers exit and fresh buyers return.
If price fails here, Ethereum could slide back toward $2,630. Below that, stronger support comes in near $2,400 if selling picks up again.
