A crypto price ticker works by holding a streaming connection to a cryptocurrency exchange, reading the last-traded price as trades happen, and redrawing an LED display — roughly once per second. Inside the case is a microcontroller (the same class of chip that runs a smart plug), a Wi-Fi radio and the screen. It reads a public price feed only: it never connects to a wallet or an exchange account.
The short version
There is no one “Bitcoin price” — each of the thousands of exchanges and pairs has its own order book. A ticker shows one exchange’s last trade, or a blend.
The device is a Wi-Fi computer driving an LED matrix. Its whole job is: connect, read the feed, redraw.
Streaming (not polling) is what makes it feel live. Turionics reads the Binance market-data API or Coinbase’s public feed (you choose in the control panel) every second.
The Binance public feed is free, needs no account, and allows 6,000 request-weight per minute per IP — far more than one device uses.
On a dropped connection a good ticker holds the last price and reconnects quietly.
There is no single Bitcoin price
“The price of Bitcoin” is not one value. Every exchange — Binance, Coinbase, Kraken and dozens more — runs its own order book, matching its own buyers and sellers. Each trade that clears on a given exchange sets a new last-traded price for that exchange. At any instant those prices differ, usually by a few dollars.
They stay close because of arbitrage: if Bitcoin is cheaper on one venue, traders and bots buy there and sell where it is dearer until the gap closes. That pressure keeps every major exchange in a tight band but never makes them identical. A ticker shows one exchange’s last trade. Turionics reads Coinbase (the default) or Binance, two of the deepest markets in crypto, and you choose which in the control panel — deeper markets move more smoothly and are more representative of where the asset is actually trading.
The device is a computer with a screen
Inside the case is a microcontroller wired to an LED display and a Wi-Fi radio. On power-up it joins your network and opens a connection to the exchange’s public price feed. That is its entire job. It does not touch a wallet or an exchange account and holds nothing sensitive — the worst thing a compromised ticker could do is show you a wrong number.
Power draw is tiny: under 5 W, about the same as a phone charger. Running one 24/7 for a year uses roughly 35–40 kWh, which at a typical US residential electricity rate works out to somewhere around $6–$8 a year.
How the price reaches the screen
A connected device can get live data two ways: it can poll (ask “what’s the price now?” every few seconds) or hold a streaming connection open and let the exchange push each update as trades happen. Streaming is what makes a ticker feel genuinely live rather than a few seconds behind. Turionics receives fresh data every second.
One thing people notice: very small moves, a few tenths of a cent, may not visibly change the digits, so the screen can look calmer than the market is. It is not lagging — the price just did not move enough to redraw a digit.
The Turionics ticker is built for this: the live price of Bitcoin and 1000+ coins, always on, on a single-colour LED display you set up once in a browser and then forget about. No app, no account, no subscription. Green is the colour most people choose.
At the size and power of a desk device, a single-colour LED matrix is the brightest and sharpest option, and it stays readable from across a room. Full-colour screens split the same power across red, green and blue sub-pixels and look dimmer at a distance; e-ink is lovely up close but too slow to feel live. The colour on a Turionics unit is a finish you pick — a red display does not mean the price is down.
What happens when the connection drops
Networks blip and APIs hiccup. A well-built ticker keeps showing the last known price and quietly reconnects, rather than blanking, freezing, or — worst of all — showing a stale number with no sign it is stale. A reliable data source matters here, which is a large part of why a deep exchange feed is a common default.
How much delay is there between a trade and the number changing?
On a normal home connection, typically under a second — the exchange pushes the update, it reaches your network, the chip parses it and redraws. Fast enough to treat as real-time for a desk device.
Does the exchange it reads matter?
Somewhat. A deep, liquid market like Binance produces a price that moves smoothly and reflects real trading. A thin market can jump around on single trades and drift from the wider market.
Is my wallet or exchange account involved?
No. The device only reads a public price feed. It has no way to touch an account, and the Binance and Coinbase public market-data endpoints it uses do not even require a login.
How often does a crypto ticker update?
A good one updates about once per second via a streaming feed. Displays that poll an aggregator “every 60 seconds” are technically tickers but do not feel live.

What it does not do, on purpose
No chart, no portfolio, no multi-asset alerts, no order entry. The moment you add those, you have rebuilt the phone app you were trying to get away from. A ticker is one number with nothing attached, and that constraint is the point. For more on why that constraint is worth paying for, see why people put a crypto price ticker on their desk. For the term itself, what is a Bitcoin ticker. Where a crypto ticker gets its price goes deeper on the feed, and what it costs to run covers the power side.
