Deciding which of the world’s two most prominent digital currencies to invest in can be a complex decision.
So far this year, Bitcoin (BTC 1.98%) and Ethereum (ETH 2.43%) have shown very similar growth. The value of Bitcoin has increased by 25% in 2025, while Ethereum has grown by 30%.
Even though Bitcoin remains the top cryptocurrency with a substantial market capitalization of $2.3 trillion, Ethereum‘s performance has been particularly strong recently. From May to September, Ethereum’s price more than doubled, easily surpassing Bitcoin’s gains. The question is: Which presents the better investment opportunity at this moment?
Past Performance
Bitcoin is widely recognized as one of the best-performing assets of the last decade, and for good reason. It achieved the highest return of any investment asset in eight of the past ten years. Its annual gains often reach triple-digit percentages.
Ethereum has also demonstrated impressive growth. Over the last five years, it has actually outperformed Bitcoin. Looking at the TradingView chart, Bitcoin has increased by a significant 938% during this time. However, Ethereum’s rise has been even more substantial, increasing by 1,059%.

Remarkably, Ethereum has consistently stayed ahead of Bitcoin, with the exception of a notable downturn earlier this year. While previous performance does not guarantee future results, the performance of Bitcoin and Ethereum over the next five years may be closer than some anticipate.
Companies with Cryptocurrency Treasuries
Another important aspect to consider is the emergence of companies with digital asset treasuries (DATs). These companies are specifically designed to acquire and hold significant amounts of a specific cryptocurrency, raising capital from investors to purchase large quantities of that cryptocurrency.
Bitcoin receives much of the attention in this area because the first DAT was Strategy (MSTR -0.20%), previously known as MicroStrategy. Starting in August 2020, Strategy began adding Bitcoin to its balance sheet. Over the past five years, it has steadily increased its Bitcoin holdings, becoming the largest corporate holder of Bitcoin worldwide, possessing 640,000 Bitcoin, approximately 3% of the total Bitcoin supply.
However, the activities of Ethereum treasury companies should not be overlooked. There are now 71 of these entities, collectively holding an estimated $22 billion in Ethereum, a figure that has more than tripled since July. Currently, these companies hold 3.5% of all Ether in circulation, making them a significant market force.
This significant increase in buying activity has contributed to Ethereum’s price surge this summer. Given the limited number of Ethereum coins available – just 120.7 million – the influx of companies committed to large-scale Ethereum purchases drove the price upward.
Ethereum’s Potential Income Stream
Ethereum possesses a potential advantage over Bitcoin: It is a proof-of-stake blockchain, while Bitcoin uses a proof-of-work blockchain. While this may seem technical and relevant only to blockchain developers, it offers a significant benefit.
This key characteristic allows Ethereum investors to generate passive income through staking. Staking involves locking up cryptocurrency for a specified period in return for rewards.
The average staking yield for Ethereum is currently 3%. While this may appear small, it can be a compelling incentive for institutional investors seeking an additional performance boost. Earning an extra 3% can significantly impact investment returns over time.
It is believed that Ethereum treasury companies can leverage this 3% staking yield to create a positive feedback loop. The more Ethereum they acquire, the more they can stake, providing them with an advantage over Ethereum exchange-traded funds (ETFs), which have previously been restricted from offering staking rewards to investors.
This income stream may justify investors paying a premium for shares of publicly traded Ethereum treasury companies. This allows these companies to attract more capital from investors at a lower cost, which they can then use to buy more Ethereum, continuing the cycle. This creates a self-reinforcing growth dynamic.
Which Cryptocurrency Should You Buy?
Currently, Ethereum’s position is compelling. It is outperforming Bitcoin both this year and over the past five years. The momentum behind Ethereum treasury companies also appears strong. Investors seem eager to accumulate as much Ethereum as possible.
Therefore, despite previous assumptions, Ethereum might be the more attractive investment option as we approach the end of 2025.
