Fiat vs. cryptocurrency

Two kinds of money

Fiat currency is government-issued money: dollars, euros, yen, pounds. Its value rests on trust in the issuing country and its central bank. Cryptocurrency is digital money recorded on a blockchain, a shared ledger maintained by a network of computers rather than a central authority. Bitcoin and Ethereum are the best-known examples.

Both can be converted into each other and into one another's units, and Currvo treats them in the same converter. But because they are issued and traded so differently, the price you are converting behaves in distinct ways.

Who sets the price

A fiat currency's value is anchored by its central bank's policy and by an enormous, deeply liquid interbank market. There are powerful institutions whose job involves keeping things orderly.

A cryptocurrency has no central bank and no official rate. Its price is set purely by supply and demand on exchanges, the venues where people buy and sell it. Nobody is steering it, which is part of the appeal to its supporters and part of the risk to its critics.

When they trade

Traditional currency markets run roughly 24 hours a day, five days a week, and close over the weekend. Crypto markets never close: they trade 24 hours a day, every day of the year, including weekends and holidays. That means a crypto value can move overnight or on a Sunday, when fiat rates are frozen.

Why crypto moves so much more

The single biggest practical difference is volatility, how much a price swings. A major fiat pair like EUR/USD typically moves a fraction of a percent in a day. A cryptocurrency can move several percent in an hour, and occasionally far more.

This has a direct consequence when you convert: the number you see can change meaningfully between the moment you check it and the moment you act on it. With a fiat conversion that drift is usually negligible. With crypto it can be the difference between two noticeably different figures, so it pays to treat a crypto quote as an estimate rather than a locked price.

Where a crypto price actually comes from

Because a cryptocurrency trades on many exchanges at once, each with its own order book, there is no single official price. What you see quoted is usually a volume-weighted average across major venues. This is why two reputable sites can show slightly different prices for the same coin at the same instant: they are averaging a living, fragmented market in slightly different ways or at slightly different moments. Small discrepancies are normal and not a sign that either source is wrong.

Stablecoins: a bridge between the two

A stablecoin is a cryptocurrency designed to hold a steady value, usually pegged to a fiat currency such as the US dollar. The idea is that one unit should always be worth about one dollar, combining the steadiness of fiat with the speed and reach of crypto. Stablecoins are widely used as a resting place between trades and as a practical way to move dollar-like value across borders. They are a useful reminder that "crypto" is not one thing: it ranges from highly volatile assets to ones engineered specifically not to move.
