Not financial, legal, or tax advice. This article explains general pricing concepts, not a prediction or recommendation for any asset. Crypto values are volatile and can fall as well as rise.
Cryptocurrencies get their value the same basic way any asset does: from what buyers and sellers agree it's worth, shaped by supply and demand, what the asset is actually useful for, how scarce it is, and how the market feels at any given moment. It all builds on the fundamentals of what a cryptocurrency is. The Bank for International Settlements has published a detailed analysis of what does and does not underpin crypto valuations.
Supply and demand
Price moves on the balance between how many people want to buy at a given moment and how many are willing to sell. A predictable supply schedule combined with rising demand tends to push prices up; the reverse pushes them down.
What makes crypto unusual is which half of that equation can move. For most goods, a price rise pulls in more supply: bakeries bake more bread, miners dig more copper. Bitcoin's issuance is fixed in code and does not respond to price at all, so demand has nowhere to go but into the price itself. The same rise that would trigger more production elsewhere produces exactly the same number of new coins per block, which is a large part of why crypto moves as violently as it does in both directions.
The question people get stuck on is what backs any of it, and the honest answer is that the question assumes something that was never true of money. The dollar has not been redeemable for gold since 1971. It is valuable because people accept it, which rests on confidence in the institution behind it and the legal requirement to pay taxes in it. Gold's industrial uses account for a small fraction of its price; the rest is thousands of years of agreement that it stores value. Crypto asks people to extend that same agreement to a scarce digital asset with no institution behind it, which is a genuinely harder sell and exactly why the price argues with itself so publicly.
Utility
An asset used for actual transactions, smart contracts, or network fees tends to have demand tied to real usage, not just speculation. The more a network is used, the more reason there is to hold its native asset.
The mechanism is more concrete than "usage is good." If a network requires its own coin to pay fees, then every person who wants to do anything on that network has to acquire some, which is structural demand rather than sentiment. Ethereum tightened this further by burning a portion of every fee, permanently destroying it, so heavy usage actively shrinks supply. Staking pulls in the same direction, since coins locked as collateral are coins not available to sell.
Utility does not float the price on its own, though, and the market is inconsistent about rewarding it. Plenty of networks with genuine users trade below assets with none, because a coin can be necessary for a network while the network is small enough that necessity does not amount to much demand. Utility gives value a floor to argue from. It rarely sets the ceiling.
Scarcity
Many cryptocurrencies have a capped or slow-growing supply built into their code, unlike currencies a central bank can print more of. Predictable scarcity is part of the appeal, though it doesn't guarantee value on its own. Market capitalization is how supply and price combine into a single size metric.
The word doing the work there is predictable rather than scarce. Anyone can write a cap of 21 million into a new token this afternoon, and its scarcity would be worth nothing, because scarcity only matters when the thing being rationed is wanted and the cap cannot be lifted. Bitcoin's limit is credible not because it is written down but because changing it would require near-unanimous agreement from people who hold the asset precisely for that limit, which is a social fact rather than a technical one.
It is also worth noticing what scarcity does to behavior. A supply that cannot expand encourages holding rather than spending, since the reasonable expectation is that units get more valuable over time. That is a feature if you are storing value and a problem if you wanted a currency people actually transact with, and it is the tension at the center of most arguments about what Bitcoin is for.
Market sentiment
Crypto markets react strongly to news, adoption trends, and broader risk appetite, which is why prices can swing sharply even when nothing about the underlying technology has changed. Before buying into any of it, it helps to have a framework for evaluating a coin.
Sentiment dominates over short horizons for structural reasons, not just because traders are excitable. Crypto trades continuously, worldwide, with no circuit breakers and no closing bell, so there is no pause during which a panic can burn itself out. It has no earnings reports to anchor a valuation, which means there is no agreed-upon number to argue back to when the price moves. And a large share of the market is leveraged, so a fall triggers forced selling, which causes a further fall. That is a feedback loop, and it works identically on the way up.
The practical implication is not that fundamentals are irrelevant. It is that they operate on a completely different clock than sentiment does, and mistaking one for the other is how people end up buying at the top of a story and selling at the bottom of the same one. Days and weeks are about mood and positioning. Years are about whether the network was worth using. Almost every painful crypto mistake comes from reading a short-term move as long-term information.
One more force belongs in this list, because it explains moves that otherwise look inexplicable: crypto trades as a risk asset. When interest rates rise or a broader market shock hits, investors sell the most speculative thing they own first, and crypto is usually somewhere near the top of that list. So the price can fall hard on a week when nothing whatsoever happened in crypto, purely because something happened somewhere else. Assets that were pitched as uncorrelated have repeatedly turned out to be very correlated at exactly the moments when that would have mattered most.
Taken together, these four forces are less a formula than a set of lenses. Nobody can tell you what a coin should be worth, and anyone offering a precise figure is selling something. What you can do is ask which of these is actually driving a given move, and whether that reason has anything to do with why you bought in the first place.
