Prediction: This Cryptocurrency Will Be the Biggest Comeback Story of 2025

Key Points

Ethereum (CRYPTO: ETH) , the world's second-largest cryptocurrency, has had an absolutely dreadful start to the year. It's still down 20% in mid-May, and has been underperforming the broader crypto market for months now.

However, a number of catalysts are coming together for Ethereum that could make it the comeback story of the year. In the second half of 2025, I'm expecting a big breakout for Ethereum. Here's why.

Spot Ethereum ETFs

It might sound simplistic, but the easiest way to gauge how much momentum a cryptocurrency has is by looking at investor inflows and outflows.

This method is available to Ethereum investors, because it is one of only two cryptocurrencies with exchange-traded funds (ETFs) based on their current spot prices . Generally, if money is flowing into these spot ETFs, it suggests rising demand and can put upward pressure on Ethereum’s price. If money is flowing out of these spot ETFs, the price of Ethereum is likely to fall. Other factors also drive Ethereum's price changes, including market sentiment and recent news, but generous ETF inflows are still a handy measuring stick.

That's why the first half of the year has been so problematic for Ethereum. Investors were moving money out of these ETFs at a rapid pace. But inflows are starting to appear again. In fact, May is shaping up to be the best month of the year, with over $100 million in new money flowing into the spot Ethereum ETFs. It's still too early to do a victory lap, but things are definitely looking better.

New blockchain upgrade

Another important catalyst is a brand-new upgrade of the Ethereum blockchain , known as "Pectra" (a combination of "Prague" and "Electra"). While blockchain upgrades are a dime a dozen these days, this one from Ethereum really resonated with investors. As soon as Pectra went live on May 7, the price of Ethereum started to soar.

There are several reasons why the Pectra upgrade has resonated so much with investors. The primary reason is that it reaffirms Ethereum's desire to boost its transaction processing capacity. This is one area where upstart rivals have really stolen a march on Ethereum, so it's important to show constant progress on this front. The upgrade also helps to make Ethereum cheaper and easier to use.
