Have you ever wondered why crypto assets (also known as virtual currencies) command such high value? Bitcoin, which traded for only a few tens of thousands of yen around 2015, hit ¥18.82 million (roughly US$125,000 at ¥150/US$1) ten years later in 2025 — and its value has kept climbing since. If you're thinking about buying crypto assets but aren't sure what's really driving this surge in value, it's natural to feel uneasy about taking the plunge.
This article is for exactly that kind of reader: it explains why crypto assets have value, and specifically why Bitcoin has earned such strong support.
Why Do Crypto Assets Have Value?
Crypto assets are legally defined as "property value" that can be exchanged over the internet. Under Japan's Payment Services Act (PSA), crypto assets are considered to have the following characteristics:
- Can be used to pay an unspecified range of people for goods or services
- Can be exchanged for legal tender
- Can be recorded and transferred electronically
- Is not itself a form of legal tender
In other words, crypto assets are not simply data — they are legally positioned as property value. So why is this value recognized in the first place? One reason is that the mechanisms that make transactions possible have been carefully built and maintained.
Crypto assets are designed as a mechanism for transferring value without going through a third party such as a bank. Transaction history is recorded electronically and managed on the network. In addition, crypto assets are not legal tender issued by a nation or central bank. As a result, crypto asset prices fluctuate based on the balance of supply and demand among users and overall market conditions.
In this way, the value of crypto assets is not created by "trust in an issuing entity," but by the fact that "users trust the underlying mechanism and actually carry out transactions." The accumulation of many people recognizing crypto assets as exchangeable property value, and of transactions actually taking place, is what supports their value.
The Value of Crypto Assets Lies in the "Mechanism"
One reason crypto assets have value is that predetermined rules are followed uniformly around the world. For example, no individual or organization can rewrite balances or arbitrarily increase the issuance amount. Transaction records are also built on a system that prevents tampering after the fact.
In this sense, crypto assets are characterized not by "trusting someone," but by being built on the premise of the mechanism itself. Because the source of value lies in the mechanism rather than in an individual or organization, crypto assets are used under the same rules across borders, and transactions take place all over the world. The value of crypto assets is not something you can see, but it becomes easier to understand once you consider that it is supported by this kind of rules and structure.
Value Arises Because There Is Demand
Value is created by "how many people want something." This basic idea applies not only to crypto assets but also to stocks, real estate, and currencies.
In the case of crypto assets, some people are drawn to the ease of sending funds, the ability to use them across borders, and a mechanism that doesn't depend on a specific administrator. As a result, more people want to hold crypto assets, trading becomes more active, and value takes shape within the market.
What matters is whether there is a reason for demand to be generated continuously, rather than a temporary trend. Because crypto assets have that reason built into their technology and rules, they are thought to be supported by many users and to have established value on that basis.
Why Is Bitcoin Particularly Well Supported?
Among the many crypto assets that exist, Bitcoin is the one that has gathered particularly strong support. Its central position is clear from the frequency with which it is covered in the news and the many instances in which it is treated as a benchmark for overall market price trends.
So why has Bitcoin alone earned this level of support? Simply having high name recognition or a rising price is not enough to explain it. Behind it lies a long track record of operation, consistent rule design, its issuance mechanism, and the fact that it is used all over the world.
Here, we'll focus specifically on the question of why Bitcoin is chosen.
There Is a Fixed Issuance Cap
One reason that supports Bitcoin's value is that there is an upper limit on the number of coins that can be issued. That cap is set in advance at 21 million coins, and this rule has been maintained from the initial issuance to the present day.
Many assets, including money itself, can be newly issued for reasons such as economic stimulus measures. While this can be a necessary aspect of supporting the economy, it also means that value can be diluted for holders. Bitcoin, on the other hand, has had its issuance cap set from the very beginning, and that rule cannot be changed arbitrarily. It is designed without any provision for operations such as "issuing more because it's needed" or "adjusting the supply depending on circumstances."
What this mechanism means is that the supply is limited. Because supply does not increase significantly even when demand rises, a structure emerges in which value is less likely to fall. Of course, having an issuance cap alone does not guarantee value. However, the shared premise that "the supply will not increase arbitrarily" can be considered one of the factors that supports long-term trust.
The Rules Have Not Changed Since Its Early Days
Bitcoin's basic rules have not changed significantly since its early days. Important mechanisms such as the issuance cap and the pace of new issuance were decided in advance, and this information is publicly available. Because anyone can check the same information, the underlying premises are unlikely to become opaque.
Furthermore, because there is no specific administrator, no individual or organization can unilaterally change the rules based on its own judgment. Changing the specification requires the agreement of many participants, which creates a system in which arbitrary changes are unlikely to occur.
Because of this structure, it is considered unlikely that the supply will suddenly increase or that the mechanism will change dramatically in the future. For example, while currencies can have their issuance volume adjusted through policy, Bitcoin is not designed with that kind of operation in mind.
This quality of having premises that are unlikely to change makes it easier to make judgments from a long-term perspective, and is one of the reasons Bitcoin is so widely supported.
The Most Widely Recognized and Used Around the World
No matter how excellent a mechanism is, its value cannot spread without users. Value only becomes established in the market once the number of users increases. In that respect, Bitcoin was the first crypto asset to become widely adopted and has a long operating track record. Through this accumulation of time, its exchange listings, supporting services, and number of users have expanded ahead of other crypto assets.
As a result, a large number of buyers and sellers gather, and a state in which trades are consistently easy to execute is maintained. Because liquidity is high (meaning trades are easy to complete), Bitcoin is often used as a price benchmark, and it is frequently treated as an indicator of overall movement in the crypto asset market.
Having a large number of users means an environment is in place where you can sell when you want to sell and buy when you want to buy. This is an important factor when treating something as an asset. In addition, when adoption by companies, institutional investors, or even nations is discussed, Bitcoin is invariably the first candidate considered. Its long track record and large market size make it the asset most likely to be chosen.
In this way, Bitcoin's value is supported not only by its underlying mechanism but also by the reality that it is actually being used.
Not All Crypto Assets Have Value
There are many types of crypto assets besides Bitcoin. Not all of these crypto assets share the same level of reliability or practical utility. Some are developed based on a clear technical purpose or business plan, some gain momentum through community-driven enthusiasm, and others are issued without their actual substance ever becoming clear.
For example,
- Malicious projects designed from the outset with the sole purpose of raising funds
- Meme coins whose prices move based on online buzz or humor
- Small-scale projects that are still in development, with an unknown future
As you can see, the backgrounds and characteristics involved vary widely. The problem arises when only the fact that a price has risen is emphasized, making it harder to see the underlying mechanism and purpose that should really be checked. One thing to pay particular attention to is the reason behind a rising price.
Unlike cases backed by something like a company's growth or expanding profits, there are cases where a price is simply pushed up by an increase in the number of participants. In such cases, a structure can easily emerge in which later participants end up becoming the exit through which earlier participants lock in their profits. When something suddenly attracts a surge of attention on social media, it's easy to feel that "it might not be too late to get in," but it is important to calmly examine the background behind the price formation.
In addition, with low-liquidity coins, even if it looks like you're in profit on screen, that doesn't necessarily mean you can actually sell at that price. Prices can also move significantly due to a small number of large trades, creating the risk that you may not be able to cash out as expected.
For this reason, one option for beginners is to start by learning about coins whose mechanisms and track records are relatively clear, such as Bitcoin and Ethereum.
Which Is Better: Crypto Assets or Stock Investing?
When starting out with crypto assets, one thing people often wonder is whether crypto or stock investing is the better choice.
First, as a premise, crypto assets are legally defined as "property value" and are, by design, a mechanism that can also be used for purposes such as payments. In practice, however, many people hold them in hopes of profiting from price fluctuations, and they are increasingly treated as an investment target.
Stock investing is a mechanism in which you contribute capital to a company and expect returns based on that company's growth and profits. Dividends (income gains) and capital gains from a rising share price are the sources of profit.
Crypto assets, by contrast, generally have no dividend-like mechanism, so gains from price fluctuations are the main source of profit. The backing for their value is also formed not by a company's earnings, but by the demand of market participants and the underlying technical mechanism.
In other words, while both can potentially generate profit from price fluctuations, they differ in "how value is created" and in "the structure of returns." Comparing the two without understanding this difference tends to focus attention only on the superficial question of "which one makes more money," making it easy to misjudge.
Rather than ranking one as superior to the other, this section organizes the differences in mechanism and risk between the two.
Differences in the Nature of Crypto Assets and Stock Investing
What matters most in understanding the difference between crypto assets and stock investing is the question of "where the value is seen to come from."
Stock investing means putting capital into a company's business and growth. Factors such as revenue, profit, and future growth potential come into play, and the structure is such that increases in corporate value are reflected in the share price. The source of value lies in the company's business activities themselves.
Crypto assets, on the other hand, are not a mechanism for generating corporate profit. At the center of their value are the technology, the rules, and the spread of the network. Factors such as how widely they are used and how many participants join affect price formation.
This difference also affects how each is viewed as an investment target. Stocks are evaluated based on a company's performance, whereas crypto assets place more weight on trust in the mechanism and how actively it is used. There is also a difference in price-movement tendencies. Stocks tend to fluctuate relatively gently, while crypto assets can see large price swings within a short period.
To sum up, it becomes easier to understand if you think of stocks as "investing in a company's growth" and crypto assets as "finding value in a mechanism and the spread of its network."
Who Crypto Assets Suit — and Who They Don't
Crypto assets suit people who can accept large price fluctuations. The current crypto asset market is smaller in scale than the stock market and has a more limited base of participants. As a result, prices can be seen to rise and fall significantly within short periods.
Given this kind of price movement, people who won't be shaken by minor fluctuations and who can take a long-term view are better suited to crypto assets. On the other hand, for people who tend to feel strong stress from price swings, or who want to place importance on backing such as stable dividends or business performance, crypto assets are likely to become a psychological burden.
That said, as the market grows in scale and regulatory frameworks develop further, price movements may become less extreme in the future than they are today. At present, however, the scale of price volatility is a characteristic that cannot be ignored. If you find yourself constantly worrying about daily price movements, there is no need to force yourself into crypto assets.
Also, starting out for the sole reason that "it seems like it could make money," without understanding the underlying mechanism and background, makes it easy to misjudge. What matters is not whether something is trending, but whether it suits your own personality and risk tolerance.
You Don't Have to Choose Just One
Crypto assets and stocks differ in how their value is formed and in their price-movement characteristics. For this reason, rather than concentrating all your capital in just one, there is also the approach of holding both with different roles — for example, using stocks for the portion where you prioritize stability and track record, and crypto assets for the portion where you're hoping for future growth and new mechanisms.
There's no need to think of it as a binary choice between crypto assets and stocks. What matters is deciding the overall balance based on how much price volatility you personally can accept. Not choosing one or the other doesn't mean you're missing out on an opportunity. Investing is not a competition against other people — what matters is whether you can keep going based on your own judgment.
Frequently Asked Questions (FAQ)
Here, we answer some frequently asked questions.
Is It Too Late to Start With Crypto Assets Now?
Whether it's "too late" for crypto assets depends on the time frame you use to think about it.
Bitcoin was created in 2009, making it a relatively new field compared with financial markets as a whole. Stocks and bonds have decades, even more than a century, of history, whereas crypto assets are still in a developmental stage.
In terms of market size too, it remains small compared with the stock and bond markets, and there is still room for expansion in areas such as regulatory development and growth in the number of participants. From this perspective, some view crypto assets as having room to grow over the medium to long term.
On the other hand, if you're hoping for a large short-term gain, it's not realistic to assume the same kind of rise seen in the early days will repeat. As the market grows larger, the nature of its price movements changes.
Therefore, it's not a stage where you can simply conclude that "it's already too late," but you should be aware that the assessment changes depending on your expected return and investment time frame.
Could the Value of Crypto Assets Eventually Fall to Zero?
No asset can be guaranteed to retain its value into the future. This is true not just of crypto assets but also of stocks, real estate, and currencies. In fact, there are real cases of stocks becoming worthless due to corporate bankruptcy, and of currency values fluctuating dramatically due to changes in a governing regime. For this reason, there is no such thing as an asset with "zero possibility of going to zero."
That said, the premise that all crypto assets would become worthless simultaneously is not necessarily realistic. In particular, major crypto assets that have been operating for a long time and are traded around the world have established a certain level of demand and market.
On the other hand, projects with a limited track record and an unclear mechanism or purpose may fail to gain users and lose their value. In fact, it is also true that many crypto assets have already disappeared from the market. Rather than lumping everything together under the single category of "crypto assets," judge each one based on its individual mechanism and how it is actually used.
Is There Any Point in Investing Even a Small Amount?
Starting with a small amount has the benefit of letting you understand the mechanism and price movements through direct, first-hand experience.
Crypto assets have large price swings, and how people feel about that movement and the psychological burden it creates vary from person to person. These are things that are hard to understand without actually moving your own money. Gaining knowledge from books and videos is important, but trading with a small amount makes it easier to grasp, in concrete terms, how prices move and what the market feels like.
Also, if you keep your investment amount small, your losses will remain limited even if the price falls. Building experience within that range provides useful material for thinking about your future decisions.
Conclusion
The value of crypto assets is supported not by a specific issuing entity, but by predetermined mechanisms and the consensus of users who trust those mechanisms. However, not all crypto assets have value in the same way — assessments vary considerably depending on the mechanism, track record, and usage of each one.
In addition, crypto assets and stocks are assets with different characteristics, and they are not something to be ranked as superior or inferior to one another. It is important to understand the characteristics and risks of each and make decisions according to your own tolerance.
There's no need to force yourself to get started, but understanding the mechanism allows you to choose for yourself how you want to be involved. Ultimately, what's required is an approach in which you judge "whether or not to hold" crypto assets on the basis of that understanding.
