By Chris MacDonald – Dec 11, 2025 at 5:32PMKey PointsA continuously shifting macro environment has provided plenty of choppiness in today's session for Ethereum and other top tokens.However, some issues around finality have become a greater cause for concern among Ethereum investors. Here's what to make of the recent issues Ethereum has been experiencing.

Unfortunately for Ethereum investors, today's high-volatility session has been tilted to the downside. Over the past 24 hours, Ethereum has declined 3.1% as of 5:00 p.m. ET. Notably, this downside move includes a 3% rally from this token's intraday low. In other words, this loss was a lot larger just a few hours ago. Let's dive into what's driving this outsize bearish sentiment around Ethereum, specifically, and why this token is the worst-performing today out of the nine largest crypto projects, as ranked by market capitalization.

Ethereum investors have plenty to pay attention to, from a macro environment that seems to constantly be changing (with yesterday's key FOMC interest rate cut being the latest catalyst to price in), to several token-specific drivers that are currently impacting sentiment. In terms of the most relevant drivers of today's bearish sentiment, I believe that concerns about Ethereum's finality, specifically the time it takes for blocks to be processed, are the most pressing concern for most Ethereum investors. Advertisement Several hours-long delays, which limit finality on the Ethereum blockchain, have some in the Ethereum community concerned. If enough developers and users decide to flip to faster and more inexpensive layer-1 networks for their applications, this network's massive moat could come under pressure. That's really the bottom line. Indeed, no matter what Ethereum founder Vitalik Buterin says about these effective outages posing no serious threat to Ethereum's overall security, they will create concern, or even panic, among many who view Ethereum as the most stable network in the market.

With Tom Lee's Bitmine buying another $112 million worth of Ethereum yesterday, there are clearly still bulls looking to take the other side of this bet. But for now at least, sentiment around the Ethereum network is declining, and there are certainly reasons for this concern.
