A simple GUI to track cryptocurrency prices.
$ go install github.com/itohi/CoinWatcher/cmd/watcher@latest
All the requirements for building Fyne apps apply.
You will need Coinmarketcap API key for this to work. They offer a free tier with 10000 API credits per month, so it should be plenty enough for casual use.
You can setup the API key using COINWATCHER_KEY environment variable at first start. Otherwise it is possible
to configure the api key using settings button.
- Save/Load coin list
- Fetch prices from Coinmarketgo
- Cache coin images
- Convert currency (requires either payed plan or fetching fiat currencies and converting that way)
