After achieving two consecutive years of triple-digit profits in 2023 and 2024, Bitcoin is on track to have its weakest performance since 2022 in 2025. The world's most popular cryptocurrency has fallen by 6% in the past 30 days and has only increased by 20% in the year as I write these lines. So what is happening? There are three reasons that could cause Bitcoin to decline.

Reason Number 1: The General Weakness of the Macroeconomy

For much of its history, Bitcoin has not correlated with any major asset classes. It can fluctuate as other assets fluctuate. This makes Bitcoin particularly attractive to investors. In most market conditions, Bitcoin can provide the potential for astronomical returns.

But that may no longer be the case. In many respects, Bitcoin may be much more susceptible to overall macroeconomic conditions than previously thought. In other words, Bitcoin will face much greater hurdles if job growth slows, if inflation continues to rise, or if tariffs lead to weaker overall growth. And that is exactly what is happening right now.

The decline of Bitcoin is entirely reasonable considering the level of interest it is receiving from institutional investors. Just a few years ago, retail investors were the ones leading the pace of Bitcoin adoption. But now, wealthy institutional investors are the ones holding vast amounts of assets, and this may explain the current obsession of the cryptocurrency market with the possibility that the Fed will cut interest rates.

Reason Number 2: Investors Are Diversifying Into Other Cryptocurrencies

Although Bitcoin still accounts for nearly 60% of the total cryptocurrency market capitalization, it is hard to ignore the level of interest that other segments of the cryptocurrency market are attracting from investors. There was a time when Bitcoin was the only game in town for institutional investors. But that is no longer the case.

For instance, consider the rise of so-called digital asset management companies. These firms do one thing: raise capital from outside investors and then reinvest that money into a specific cryptocurrency. This summer has seen the emergence of fund management companies for Ethereum, Solana, and XRP. All that money could have flowed into Bitcoin.

Or, for example, consider the sudden interest in stablecoins. Recent laws may lead to a boom in stablecoin investment. According to a recent report from Citigroup, the market size of stablecoins could soar to $3.7 trillion in just a few years. This is also the amount that could have been funneled into Bitcoin.

This diversification from Bitcoin into other cryptocurrencies is not a new phenomenon. In fact, this is exactly the pattern that the cryptocurrency market has witnessed during the previous bull run of 2020-2021. Bitcoin surged first, followed by Ethereum, and then lower market cap altcoins. Ultimately, there was a speculative boom in meme coins and NFTs.

Reason Number 3: The Bitcoin Cycle Is Underway

This brings us to perhaps the most concerning reason for Bitcoin's decline: the four-year cycle of Bitcoin is approaching a price level that typically sees a decrease. If you are a Bitcoin investor, that is the last thing you want to hear, because it means that Bitcoin's recent decline could be a harbinger of what is to come at the end of 2025.

Nothing is guaranteed in investing, but looking at history, the four-year Bitcoin halving event has been a catalyst for a strong bull run. So far, there have been four halvings, and the price rise following a halving typically lasts from 12 to 18 months, followed by a classic "blow-off top" - a rapid, strong price surge, followed by a rapid, significant drop. In that case, Bitcoin reached a new all-time high before ultimately collapsing in value. For example, in 2022, Bitcoin dropped sharply by 64% after hitting a new all-time high in November 2021 following the halving in May 2020.

The problem, to put it bluntly, is that the most recent Bitcoin halving event occurred in April 2024. This means we have already gone through 17 months in the period where prices are expected to rise rapidly. In the worst-case scenario, there may be just a few months left until Bitcoin peaks again and the entire cycle starts over.

Certainly, there are many signs that the peak of this boom is forming. Billions of dollars are being invested in highly speculative digital assets, loss-making businesses are quickly transforming into digital asset management companies, new cryptocurrency firms are rushing to go public before the cryptocurrency IPO market closes, and Wall Street is quickly reassuring investors that "this time will be different".

So, if you are considering investing in Bitcoin right now, be sure to conduct thorough due diligence and keep your investment small. There are some very concerning signs that Bitcoin's pullback this summer could be a warning sign for a challenging and volatile fourth quarter.
