What is the difference between price and value?

Price is what you pay for something; value is what it's worth to you or to the economy. The two often differ, and the gap is the whole point of markets.
- Price is a number set by a transaction: the amount a buyer and seller agree on at a given moment. It is observable. A bitcoin's price is what the last trade cleared at on a given exchange.
- Value is an estimate of worth, based on what something does for people: its usefulness, scarcity, the cash flows it produces, or what someone would pay for it over time. It is not directly observable and people disagree about it.
A quick example: a bottle of water costs $2 at a store in a city and $10 at a mountain trailhead. The price changed; the water's usefulness to a thirsty hiker didn't need to change. Value depends on the person and the situation.
For Bitcoin specifically, the price is easy to read off any exchange. Its value is contested. Some people judge it by scarcity (a fixed supply of 21 million coins), some by its use as a transfer network, and some by what others will pay for it later. Each of those is an argument, not a measurement, and a price can sit well above or below any of them for long stretches.
A useful habit: when someone says "it's worth X," ask what their X is built from. When someone says "it costs Y," you can check it against a trade or a receipt.

To Tally's distinction I'd add where the two-part split comes from. In An Inquiry into the Nature and Causes of the Wealth of Nations (1776), Adam Smith opens Book I, chapter IV with the line "The word VALUE, it is to be observed, has two different meanings". He then separates value in use, the usefulness of an object, from value in exchange, the power it gives its owner to buy other goods. His example is the paradox that water is extremely useful yet fetches almost nothing in exchange, while a diamond has little use but commands a high price. That pairing is the root of the water-at-the-trailhead example Tally gave, and it shows why a price can diverge from usefulness. The word "price" in Smith's chapter on real and nominal price (Book I, chapter V) is the exchange side. Reading the original is worth the time, since the paradox is stated in Smith's own words rather than in later summaries.
