Bitcoin (BTC): the First Cryptocurrency Explained
Bitcoin is the first cryptocurrency, launched in 2009 under the pseudonym Satoshi Nakamoto with a 21 million cap. Learn what BTC is and where to check it.
This is the hub for the five assets we cover in depth: Bitcoin, Ethereum, Tether, BNB and Dogecoin. Prices move by the second, so we do not print them here. Each asset page carries a live market widget and links to the official Binance markets page.
A market page answers one narrow question: what is this asset trading for right now, and how much activity stands behind that number? The usual headline figures are the last traded price, the range the price covered over the past 24 hours, traded volume, and the depth of resting orders on each side of the book. On an exchange, each of those figures belongs to a specific trading pair rather than to a coin in isolation, which matters more than it sounds. BTC/USDT and BTC/USD are different markets with different liquidity, and on any given day they can tell slightly different stories.
Because those figures change continuously, this site does not print them in the body text. Instead, each asset page runs a market widget that reads a live quote from a public market API, and links out to the official exchange pages where you can inspect pairs, order-book depth and historical candles yourself. That division of labour keeps the written guidance stable while the numbers stay current.
We keep detailed English pages for the assets readers ask about most often. Each page explains what the asset is, how it is used and quoted, how its supply works, and where to verify market data on official sources. This hub is simply the entry point that ties them together.

A hard-coded price is out of date the moment it is written, and a stale price is worse than no price at all when someone is deciding whether to trade. That is why every quote on BinanceGuide comes from a live client-side widget, and why our text says to check live market data or the official site rather than naming a figure. If you ever see a specific price inside the prose of one of our pages, treat it as an editorial error and tell us through the contact address on our about page.
The same rule applies to percentage moves, market capitalisation rankings and other fast-changing statistics. They can be useful, but only when a reader can see where the number came from and when it was measured, so we point you to sources that show both.
Two numbers describe the same market from different angles, and mixing them up causes a lot of confusion. The last traded price is simply the most recent match between a buyer and a seller, so it reflects one transaction, not a guarantee that you can fill a large order there. Volume tells you how much activity sits behind the price, and thin markets can travel a long way on very little buying. Depth tells you how much size you can trade before the price starts to slip.
The official Binance markets page is the reference point for anything listed on Binance, and the official converter handles straightforward unit conversions such as USDT to USD. For assets with their own foundations, the project websites publish the primary documentation and network data. When a headline and an official page disagree, trust the official page, and never move funds on the strength of an image someone sent you.
The widgets on our asset pages read a public market API each time the page loads, so the numbers you see are current at the moment you load them. The written text deliberately contains no prices, because any figure typed into a paragraph would be stale within seconds of publication.
They are two separate markets. One is priced against a dollar-pegged stablecoin, the other against US dollars on venues that support fiat. Liquidity, fees and the small gap between USDT and one dollar all feed into the difference, so neither pair is automatically the more correct one.
Bitcoin (BTC), Ethereum (ETH), Tether (USDT), BNB and Dogecoin (DOGE). Each asset page explains the asset itself, how its supply or network works, and how to check its market data through official sources.
Public market pages on official exchange sites show prices, pairs and order books without signing in. Placing an order or using account features requires an account on that platform. This site has no accounts of its own and never asks you to log in.
No. We avoid forecasts, target prices and profit claims entirely. Our pages explain how markets and products work and where to find official information, and they leave every trading decision to you, ideally after you have considered your own circumstances and risk tolerance.
Use the official converter, which shows the rate it will apply before you confirm. For background on how conversion, spreads and regional pricing work, see our conversion guide, which explains the mechanics without publishing a fixed rate of its own.
