“Nothing can beat cryptocurrency in the long run.”

“Crypto is the best long-term investment.” Here’s how to respond to that certainty.

Cryptocurrencies: promise of gains or long-term illusion?

Over the past decade, cryptocurrencies—especially Bitcoin—have generated a great deal of attention. Some present them as the ultimate asset class, the one that will outperform all others over the long term. And it’s true that Bitcoin’s past performance is spectacular. But can we really claim that no other investment can compete over the long run? A rigorous, nuanced analysis is required.

Impressive historical returns

From a purely quantitative standpoint, Bitcoin has experienced explosive growth. Between 2013 and 2023, it posted cumulative returns of several thousand percent, far surpassing stocks, bonds, and gold. These figures, widely shared on social media, are often presented as proof that cryptocurrency is unbeatable in the long term.

However, this period also corresponds to its initial adoption phase, during which any emerging asset can experience significant speculative increases. It’s risky to extrapolate these returns indefinitely into the future.

A volatility that undermines reliability

What enthusiastic supporters often fail to mention is the extreme volatility of these assets. Bitcoin has experienced corrections of more than 50% on many occasions, sometimes within just a few weeks. An investor who bought at the wrong time may have had to wait years to recover their initial investment. For example, after reaching USD$ 64,000 in April 2021, Bitcoin fell below $30,000 just a few months later.

This instability makes it difficult to include in a retirement or long-term financial planning strategy. Unlike stocks that pay dividends or bonds that generate interest, cryptocurrencies pay no income. Their value is based solely on supply and demand — in other words, on speculation.

Traditional assets remain pillars

Historically, a well-diversified portfolio of stocks and bonds has helped build lasting and predictable wealth. The S&P 500, for example, has delivered an average annualized return of about 10% for nearly 100 years — with fluctuations, but also an underlying economic logic: business growth, productivity, and innovation.

Bonds, on the other hand, play a stabilizing role and provide fixed income, useful for retirement or during periods of uncertainty.

In contrast, cryptocurrencies are difficult to assess and are subject to technological risks (hacking, coding errors), regulatory risks (government bans), and reputational risks (market manipulation, exchange collapses such as FTX).

The importance of diversification

Cryptocurrencies can be part of a portfolio — but in a measured proportion, often between 1% and 5% for experienced investors. In that case, it’s an intentional speculative bet, but not a central pillar. Relying solely on them to achieve long-term goals is risky and deviates from the proven principles of wealth management.

In conclusion

No, cryptocurrency is not a scam, nor is it a phenomenon to ignore. But portraying it as the only path to long-term wealth is equally problematic. Traditional assets have stood the test of time — they provide income streams, strong regulation, and valuation based on fundamentals. Cryptocurrency has its place in a modern portfolio, but it cannot, on its own, claim to dethrone all other investments.
