Bitcoin Is Down 3% in October and Ethereum 12%. Which Should a First-Time Buyer Pick?

In October 2026, both Bitcoin and Ethereum have experienced declines, with Bitcoin (CRYPTO: BTC) decreasing by 3% and Ethereum (CRYPTO: ETH) falling by 12%. This disparity in their performance presents a challenge for first-time investors who are trying to decide which cryptocurrency to purchase.

For newcomers to the cryptocurrency market, the choice between Bitcoin and Ethereum can be daunting, particularly during a downturn. The popular Reddit thread titled “ELI5: Why invest in Bitcoin when Ethereum exists?” illustrates the confusion surrounding these two cryptocurrencies. Bitcoin, recognized as the first cryptocurrency, is often viewed as a safer investment, while Ethereum is known for its broader functionality.

The volatility of these digital assets is a key factor that new investors need to consider. It is essential to assess how much of a decline one can tolerate without panicking. In the past year, Bitcoin has decreased by 28%, while Ethereum has dropped by 40%. Investors who react hastily during market dips risk solidifying their losses rather than recovering when the market rebounds.

In terms of daily price fluctuations, Bitcoin generally sees movements of about 3%, whereas Ethereum typically swings around 4%. This means a $1,000 investment could fluctuate by approximately $28 for Bitcoin and about $39 for Ethereum each day. During market downturns, these differences in volatility become even more significant. For instance, in early 2026, a 29% drop in Bitcoin would reduce a $1,000 investment to around $712, while a 38% decline in Ethereum would lower the same investment to about $617. Such trends can be crucial for hesitant investors deciding which cryptocurrency to sell in tough times.

Looking at longer-term performance, Bitcoin has appreciated by approximately 34% over the last five years, while Ethereum has seen a decline of 43%. However, over a decade, Ethereum has experienced a remarkable gain of about 20,390%, compared to Bitcoin's increase of 11,644%. This indicates that while Ethereum can yield substantial profits, it also poses a higher risk of significant losses.

First-time buyers essentially face three options for their initial investment: they can choose to invest entirely in Bitcoin, entirely in Ethereum, or create a diversified portfolio that includes both.

The first option is to invest solely in Bitcoin. Many investors favor Bitcoin for its perceived scarcity and a capped supply of 21 million coins, with over 20.1 million already in circulation. Bitcoin's market capitalization stands at approximately $1.6 trillion, significantly higher than Ethereum's $285 billion. Additionally, Bitcoin is accessible through regulated spot exchange-traded funds (ETFs), which collectively hold around $105 billion, making it a more stable choice for those seeking lower volatility.

The second option is to invest entirely in Ethereum. Some investors prefer Ethereum due to its blockchain capabilities that support a variety of applications, stablecoins, and tokenized funds—features that Bitcoin does not offer. Ethereum holders can also stake their coins to contribute to network security and earn rewards. However, Ethereum does not have a fixed supply cap, and its ETFs have seen significant outflows, currently holding about $15 billion. This option may attract buyers who are comfortable with higher volatility.

The third choice is a balanced investment strategy, which is gaining traction among new investors. This approach typically involves allocating a larger portion of funds to Bitcoin while still gaining exposure to Ethereum's potential growth, thereby reducing the pressure to choose one over the other.

Some potential buyers might be drawn to Ethereum simply because its price per coin appears lower at $2,333 compared to Bitcoin's $80,268. However, it's important to note that both cryptocurrencies can be purchased in fractions, so the price alone does not determine their value. Furthermore, the larger drop in Ethereum's price during October does not guarantee a stronger recovery.

Transaction costs also play a vital role, as trading fees and ETF expense ratios can vary widely. Any fees incurred upfront will extend the time it takes to recover on a $1,000 investment.

In conclusion, for most first-time buyers, Bitcoin is often considered a more sensible starting point, with Ethereum as a secondary option. The primary consideration should be the size of the investment; cryptocurrencies should typically make up only a small portion of an individual's savings, with emergency funds prioritized. While opting for Bitcoin may mean missing out on Ethereum's potential upside, especially if its applications continue to develop, Bitcoin generally offers a more stable introduction to the cryptocurrency market for newcomers.
