Has Bitcoin Become a Normal Asset?

What Would “Normal” Have to Mean?

Calling an asset “normal” is not really about how it feels. It is a set of things we can measure.

A normal portfolio holding should not move three times as much as the stock market . It should not lose half its value while stocks lose a fifth. And if it is meant to diversify a portfolio, it should not simply move in the same direction as the assets already in it.

Our study window starts on July 11, 2024, so it covers a little more than two years. Bitcoin gained 38.9% over that period, equal to 16.5% a year.

But the return itself is not the most interesting number. The more useful question is how Bitcoin produced that return.

Bitcoin Is Calmer — but Still Far More Volatile

Volatility tends to come in waves. Quiet periods are usually followed by quiet periods, while turbulent markets tend to stay turbulent for a while. If Bitcoin is becoming a calmer asset, that should show up in its rolling volatility.

It does. The median rolling volatility falls from 52.9% in the first half of the period to 43.2% in the second half. Across the full period, Bitcoin’s annualized volatility was 45.6%.

The comparison with stocks puts those numbers into perspective. The S&P 500 is currently at around 14%. Bitcoin has become roughly one-fifth less volatile than it was two years ago, but it still moves about three times as much as the stock market.

That matters for a portfolio. A position that moves three times as much as an index fund can affect total portfolio risk far more than its weight alone suggests.

The drawdowns tell a similar story. Bitcoin’s largest peak-to-trough decline during the period was −53.0%, reached at the end of June 2026. The S&P 500’s largest decline was −19.0%.

The difference becomes even clearer when looking at the recovery required. After a 53% loss, Bitcoin needs to gain about 113% just to return to its previous high. After a 19% loss, the S&P 500 needs about 23%.

Bitcoin Moves More With Stocks Than With Gold

Volatility is only part of the question. The other issue is what role Bitcoin plays when other markets move.

There are two common ways to think about Bitcoin. One is as digital gold, an asset that moves independently of traditional markets. The other is as a high-risk asset that rises and falls with investors’ appetite for risk, much like technology stocks.

Over the full period, Bitcoin’s correlation with the S&P 500 is 0.42 and its correlation with the Nasdaq 100 is 0.41. Its correlation with gold is only 0.14. So over this period, Bitcoin moved about three times more closely with stocks than with gold.

But the average hides a lot of movement. The rolling correlation with stocks ranged from 0.24 to 0.59, the one with gold from −0.04 to 0.51. In the most recent 90-day window the order had even reversed: 0.51 with gold versus 0.28 with the S&P 500.

That does not tell us whether Bitcoin has entered a new long-term regime, because one 90-day window is not enough to answer that question. What it does show is that Bitcoin does not have one stable relationship with other assets.

A more direct test is what happens on the worst stock-market days. On the 20 worst days for the S&P 500 during the period, the index lost an average of 2.64%. Bitcoin lost 3.05% on those same days and finished lower on 80% of them. Gold gained 0.06% on average.

This is not how a hedge behaves. On the days when a portfolio was under the most pressure, Bitcoin generally moved in the same direction and made the loss slightly larger. Gold behaved differently on those days.

So Bitcoin may be becoming more established, but the data do not show it becoming a diversifier in the usual sense. During this period, it behaved more like a high-risk position tied to overall risk appetite.

Bitcoin Is the Established Asset Within Crypto

The third change is easier to see when we look at Bitcoin’s position inside the crypto market.

Of the 103 coins that were already trading when our window began, only 8, or 7.8%, outperformed Bitcoin over the same period. Looking at all 309 coins with at least 400 days of history gives 2.9%. That comparison is less useful, however, because coins launched later had less time to compete with Bitcoin over the full period.

The altcoin season index tells a similar story. It measures how many of the 50 largest coins outperform Bitcoin over 90 days. On September 4, 2026, it stood at 37 out of 100. Over 696 days up to that date, there were 5 altcoin seasons lasting a total of 26 days, compared with 36 Bitcoin seasons lasting 250 days.

Bitcoin therefore led its own market on almost ten times as many days as the broad altcoin market did.

That does not mean Bitcoin became safe. It means that, within crypto, Bitcoin has increasingly taken the more established end of the market.

What This Data Cannot Tell Us

The main limitation is the time period.

Two years and two months include one major drawdown and one recovery. They do not include a full halving cycle or a multi-year bear market. Our Bitcoin prices go back to 2017, but our daily stock data does not, so this study cannot compare today’s market with 2017 or 2021 on the same terms.

That matters. A claim that Bitcoin’s volatility is falling over the long term would need a much longer history. What we can say is more limited: volatility declined within this particular period.

There are two other limitations. First, the comparison with other coins includes only coins that still trade, so the 7.8% figure does not capture coins that disappeared. Second, a correlation of 0.42 is only an average. The rolling correlation moved a lot during the period, so a portfolio built around the average alone would assume a relationship that often looked different.

The Short Answer

Bitcoin has become somewhat more normal, but the change is limited.

It is less volatile than it was two years ago, it has become more established within the crypto market, and its role in a portfolio is easier to describe.

But it is still about three times as volatile as the stock market, and its largest drawdown was almost three times as deep as the S&P 500’s. On the worst stock-market days, Bitcoin usually fell as well.

The arithmetic shows what that means at the portfolio level. At 45.6% annualized volatility, a 5% weight in Bitcoin carries about as much volatility as a 16% weight in the S&P 500, looking at volatility alone and ignoring how the two move together.

The useful question is therefore not whether Bitcoin has matured. It is how much risk a given weight adds to a portfolio.
