Bitcoin Price (Plasma 5 widget)
KDE Plasma 5 widget that shows the bitcoin price in EUR, fetched from the CoinGecko API.
Display
| Situation | Display |
|---|---|
| Price up compared to the previous reading | green |
| Price down compared to the previous reading | red |
| Price unchanged (or first reading) | grey |
| API failure (network error, 4xx/5xx, rate limit 429) | -- |
Format: 68,969 € (thousands separators follow the system locale, rounded to
whole euros) preceded by the bundled Bitcoin icon in the compact and full
representations.
Configuration
- Refresh interval (minutes) — default 5, minimum 5, maximum 1440. The 5-minute floor exists because the CoinGecko API allows one request per 5 minutes. A hint text in the config dialog explains this.
Configurable via right-click on the widget → Configure Bitcoin Price… → General.
Installation
Graphical
Double-click bitcoin-price-1.1.0.plasmoid in Dolphin (Plasma installs it to
~/.local/share/plasma/plasmoids/ automatically). The latest build is attached
to the v1.1.0 release.
Terminal
kpackagetool5 --type Plasma/Applet --upgrade bitcoin-price-1.1.0.plasmoid
# Then restart the shell if needed:
plasmashell --replace &
Upgrading an already-installed widget requires --upgrade (--install fails
when the plugin id already exists).
Uninstall:
kpackagetool5 --type Plasma/Applet --remove nl.a14r.bitcoinprice
Notes
- The API URL uses
vs_currencies=eur. The original request referenced ausdURL, but the requirement was "price versus the euro" with a €-sign; showing a dollar amount under a € sign would be wrong. - The trend comparison is made against the last known price. After an API failure that reference is kept, so the color is correct again as soon as fresh data arrives.
- Without a CoinGecko API key the API may occasionally return 429; the widget
shows
--until the next successful poll. - Tested on Plasma 5.27 / Qt 5.15. Plasma 6 is expected to work but is untested.
Debugging
The widget logs to the plasmashell journal:
journalctl --user -u plasma-plasmashell.service | grep bitcoinprice
Expected lines: started, refresh interval: N minutes, fetched EUR <price>,
or fetch failed, HTTP status: <code>.
